Description simonis 2008-01-24 15:45:40 UTC

The gdb-engine of NetBeans aborts a debugging session if the underlying debugger issues a warning. This should be
handled more gracefully (i.e. present the warning to the user and ask him if he wants to proceed or not).

I'll attach some files which demonstrate the behaviour:

gdb_command_line.txt
--------------------
This is what gdb displays on the comamnd line if I debug the same program. You can see the warning, but there's no core
and I can "step" to the next instruction.

gdb_helper* and gdb-cmds8219.log_1
-----------------------------------
The log-files at the time when the debugger stopped at the breakpoint and the following dialog appeared:
"The GDB Debugger has reported a corrupted stack. The debug session must be terminates" <OK>

gdb-cmds8219.log
-----------------
The log file after I pressed the <OK> button.

I could solve the problem by using a newer version of gdb (6.6 instead 6.3) but that doesn't change the fact that the NB
gdb engine shouldn't abort execution because of a warning.

Regards,
Volker

Comment 6 _ gordonp 2008-02-04 17:54:10 UTC

I don't have a gdb 6.3 on my Ubuntu Linux system and can't easily
build it. The sources depend on termcap and ubuntu doesn't have a termcap in its package
repository. Since my goal of building it was to verify that gdb aborted when this situation
occurred, and since it no longer happens with gdb 6.6 (our reference version on Linux), I'm
closing as WONTFIX.
