Mysterious...

I'm using GCC 10.2.0 and only KDevelop was build with

CMAKE_BUILD_TYPE=Debug
CMAKE_CXX_FLAGS_DEBUG=-Og -g -fsanitize=address,undefined
CMAKE_C_FLAGS_DEBUG=-Og -g -fsanitize=address,undefined

All other dependencies, most notably Qt and the KDE frameworks are provided 
from Archlinux distro packages.

Cheers
