Hi all,
I seem to be having a problem while debugging a small project. If I have compile in Debug mode and select Start from the debug menu, the program exits with a segfault (expected). However, if I place a single breakpoint anywhere in the project and then Start debugging, Code::Blocks itself gets a segfault. Here is a full backtrace with the latest nightly (rev 5394) compiled with debug:
...

When I debug my application directly from gdb, I get the following:
Program received signal SIGSEGV, Segmentation fault.
0x000000000040bd9e in OS_LinSerial::SigIOHandler (iSigno=29, sitInfo=0x7fffffffd360, vpContext=0x7fffffffd230)

550 unsigned int uiMaxRead = s->uiBufferLength - s->uiCurrentBufferLength;
(gdb)
Is there some magical setting I'm missing? It's very annoying when I lose changes I've made to my project because Code::Blocks itself crashed. I would be glad to be of assistance with further bug reports.
Thanks.
