Comment 2 Marian Mirilovic 2010-05-18 13:12:49 UTC
Once again - correct steps to reproduce:
- I had opened MemoryView project
- CLass breakpoint in group 'xxxx' and another line breakpoint inside
constructor
- started debugger
- slected Breakpoint's group node 'xxx' and pushed 'Delete All' from context
menu
- continue in debugging
- finish debugging session (close the debugging application)
-> exception rises
