gdb <value optimized out>

[G VM]

I think I already found this out myself:

Found this in /usr/share/apps/cmake/modules/FindKDE4Internal.cmake
1076    set(CMAKE_CXX_FLAGS_DEBUG          "-g -O2 -fno-reorder-blocks -fno-schedule-insns -fno-inline")

:s DEBUGFULL does not have -O so that probably will fix it.

Thanks for your hint... I will keep you posted.

When I create the project IIRC I can't choose for debugfull. I used Debug.
Can I just grep for Debug and replace that with debugfull?

Sorry for my ignorance.

And thanks for your help!
