Description smjert30 2015-10-11 09:26:21 UTC 
Description of problem:
Stepping C++ source code of my project inside QtCreator 3.5.0.
The program is compiled with Clang 3.5.0 in Release With Debug Info.
GDB crashes when trying to step over SDL_PollEvent call, only when done inside QtCreator, if gdb is launched via command line the crash doesn't happen.

I can provide the source code if needed.

Version-Release number of selected component:
gdb-7.9.1-19.fc22

This is part of my source code, the necessary bits, that makes gdb crash.
Comment 15 Jan Kratochvil 2015-10-12 17:39:44 UTC 
It is invalid DWARF generated by clang; but sure GDB should not crash on it:
