Created attachment 164613 [details] A gdb debug session which triggers the behavior Product Version: NetBeans IDE 8.2 (Build 201705191307) Updates: NetBeans IDE is updated to version NetBeans 8.2 Patch 2 Java: 1.8.0_131; Java HotSpot(TM) 64-Bit Server VM 25.131-b11 Runtime: Java(TM) SE Runtime Environment 1.8.0_131-b11 System: Linux version 4.4.0-81-generic running on amd64; UTF-8; en_US (nb) In some scenarios, complex C++ with templates render gdb to issue a SIGINT to the debugged process, hanging the gui and display repeating various error messages when hitting "Terminate" icon. Two messages examples: --8< The program is not being run. The program is not being run. The program is not being run. The program is not being run. >8-- and --8< The program is not being run. No registers. No registers. No registers. >8-- I addition there seem to be a Java exception in: --8< java.lang.ArrayIndexOutOfBoundsException: -1 at java.util.concurrent.CopyOnWriteArrayList.get(CopyOnWriteArrayList.java:387) at java.util.concurrent.CopyOnWriteArrayList.remove(CopyOnWriteArrayList.java:494) at org.netbeans.modules.cnd.debugger.common2.debugger.breakpoints.NativeBreakpoint.removeChild(NativeBreakpoint.java:530) at org.netbeans.modules.cnd.debugger.common2.debugger.breakpoints.NativeBreakpoint.primDelete(NativeBreakpoint.java:1751) at org.netbeans.modules.cnd.debugger.common2.debugger.breakpoints.BreakpointManager.deleteHandler(BreakpointManager.java:1487) at org.netbeans.modules.cnd.debugger.common2.debugger.NativeDebuggerImpl.preKill(NativeDebuggerImpl.java:1280) at org.netbeans.modules.cnd.debugger.gdb2.GdbDebuggerImpl.kill(GdbDebuggerImpl.java:708) at org.netbeans.modules.cnd.debugger.gdb2.GdbDebuggerImpl$6$1.onExit(GdbDebuggerImpl.java:803) at org.netbeans.modules.cnd.debugger.gdb2.mi.MICommandManager.dispatch(MICommandManager.java:200) at org.netbeans.modules.cnd.debugger.gdb2.mi.MIProxy.dispatch(MIProxy.java:188) at org.netbeans.modules.cnd.debugger.gdb2.Gdb$MyMIProxy.dispatch(Gdb.java:697) at org.netbeans.modules.cnd.debugger.gdb2.mi.MIProxy.result(MIProxy.java:193) at org.netbeans.modules.cnd.debugger.gdb2.mi.MIProxy.processLine(MIProxy.java:157) at org.netbeans.modules.cnd.debugger.gdb2.Tap$4.run(Tap.java:369) Caused: java.lang.Exception: when processing line: 468^exit at org.netbeans.modules.cnd.debugger.gdb2.Tap$4.run(Tap.java:371) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:1443) at org.netbeans.modules.openide.util.GlobalLookup.execute(GlobalLookup.java:68) at org.openide.util.lookup.Lookups.executeWith(Lookups.java:303) at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:2058) >8-- The reproducing steps are: - insert one breakpoint so that the all bt frames has debugging symbols up to it - insert another breakpoint so that when is hit it falls behind the first one but there are some intermediary frames which don't have debugging symbols - start a debugging session; It should stop at the first breakpoint - hit "Continue"; Now it should reach the second breakpoint - now hit a series of "Step over" so that the debugger would reach one of the intermediary frames which don't debugging symbols. I would expect to be informed that the frame is without debugging symbols and possibly draw a button to show dissassembly - from here the things get wired. Most of the time "Step over" start to behave like "Continue" and runs until the first breakpoint is reached - finally, after a "Step over" or "Continue" nothing happen (the gui hangs), the variable view is empty and the only option is to hit the "Terminate" button. - the error window with repeating debugger errors are being displayed. Looking in the debug session files, towards the end, there can be seen the message: --8< ~"\nProgram" ~" received signal SIGINT, Interrupt.\n" >8--. With Eclipse or plain gdb, the same binaries and breakpoints the debugging session behaves correctly. The crash was also reported directly from the product here http://statistics.netbeans.org/analytics/exception.do?id=854271 .
Hello aganin, I'm trying to investigate the issue by myself. For this I've cloned the http://hg.netbeans.org/main-silver/ branch (btw, is this the proper branch?!), tried to build the platform from from there I'm stuck. I was looking for documentation or some tutorial but I didn't manage to find something suitable. Can someone, please, pinpoint some documentation about how to debug a Netbeans module or at least some hints about what shall I try next? Thanks!

Hi, You can try following steps. Make sure that you have - JDK 8 - ANT 1.9.6 Build NetBeans by command: cd main-silver ant build-nozip Netbeans will be in folder: nbbuild/netbeans Copy nbbuild/netbeans to some folder (for example netbeans-trunk). Run netbeans-trunk/bin/netbeans Open 2 projects: - main-silver/cnd.kit - main-silver/nbbuild Open needed C/C++ modules by clicking in C/C++/Libraries (for example C/C++ Debugger Common). Set needed breakpoints. Run nbbuild project. Edit some sources in C/C++ Debugger Common. Build C/C++ Debugger Common. Run nbbuild project to check your changes. Tip. To open sources by stack: - open window/debugging/analyze stack - copy stack and paste in analyze stack window - all lines in the window will be clickable Alexander
I forgot one step: - add Tools/NetBeans Platform in folder main-silver/nbbuild/netbeans with name NetBeans_IDE_CND_Dev
Can you try to use latest dev version first& It can be downloaded at http://bits.netbeans.org/dev/nightly/latest/
With the latest build (NetBeans IDE Dev (Build 201711260002)) the issue seems fixed. Only the notification about the no-symbols frame debug attempt remained, but this is another issue. There is any Netbeans official release planned? I've also manage to build Netbeans from main-silver (thanks Alexander Simon) but I'm stuck at "- add Tools/NetBeans Platform in folder main-silver/nbbuild/netbeans with name NetBeans_IDE_CND_Dev" step. Where must I add the "Tools/NetBeans Platform"? If it refers to the Netbeans's menus then there is no "NetBeans Platform" entry in the "Tools" menu.
