In .kdesrc-buildrc, I have also a like cxxflags # -fsanitize=address -fsanitize=signed-integer-overflow -fsanitize=bounds-strict -fsanitize=undefined -fsanitize-recover=address That line removes the -O2 from the compiler options. Added manually in the way of cxxflags -O2 -mtune=native # -fsanitize=address ..... I "only" get 10 seconds less, 22 seconds with the patch applied.
