internal compiler error: Segmentation fault

Upgrade your compiler as it is buggy and crashing on valid c++ code.

@gfxx Your compiler is crashing. Start by reinstalling the GCC tools.

thanks to all ..... on Kits selector on tabs "Compilers" "autodetect" I have a lot of Clang (from 16 to 9) GCC (from 16 to 9) ... in "manual" "C" GCC 9, clang-9, in "C++" the same ..... correct path is /usr/bin/clang-9?

need to leave out all other GCC version?
