I've tried, rebuilding both the DEBUG build of my project and the underlying static wxWidgets DEBUG build too, adding "-Wl,-no_compact_unwind" (without quotes) in the IDE's linker options for my project and his comment is here
Mimsy were the Borogoves - why is "mimsy" an adjective?

Now you're in GDB's TUI mode.
Basically, a "canary" random value is stored upon function entry just before the "return address" slot; a buffer overflow from a local variable, in order to touch the return address, would This is what causes the error message. -- Best regards, Andrey Tarasevich Yep.Thats was the problem.Thanks for your help Andrey.

This could be caused by corrupting a pointer higher up on the stack.

Once you overflow a buffer and corrupt the stack, the proper return address is destroyed.

When the debugger tries to figure out which function this address is in, it fails, because the address is not in any of the functions in your program. Usually, the debugger can still perform basic functions: It can show you registers and memory in your program, it can still single-step and set breakpoints, and so on. He is able to make the jump so its not a canary and aslr is pretty obvious when you trying to determine a good return address. –rook Jan 6 '12 at Gdb Cheat Sheet share|improve this answer edited Apr 3 '14 at 18:36 answered Apr 3 '14 at 15:30 chux 46.4k63180 If he's to avoid naked magic numbers, he should avoid them in
