Description of problem: ccache changes the order of arguments passed to the compiler, thus potentially changing the compiled output. Version-Release number of selected component (if applicable): ccache-4.7.4-1.fc38.x86_64 How reproducible: Always Steps to Reproduce: 1. cat > foo.c #if _FORTIFY_SOURCE == 0 # warning "_FORTIFY_SOURCE is 0" #else # warning "_FORTIFY_SOURCE is non-zero" #endif unsigned foo; 2. ccache g++ -O2 -flto=auto -grecord-gcc-switches -U_FORTIFY_SOURCE -Wp,-U_FORTIFY_SOURCE -Wp,-D_FORTIFY_SOURCE=3 -o foo.o -c foo.c Actual results: foo.c:4:3: warning: #warning "_FORTIFY_SOURCE is non-zero" [-Wcpp] 4 | # warning "_FORTIFY_SOURCE is non-zero" | ^~~~~~~ Expected results: foo.c: warning: -D_FORTIFY_SOURCE defined but value is too low foo.c:2:3: warning: #warning "_FORTIFY_SOURCE is 0" [-Wcpp] 2 | # warning "_FORTIFY_SOURCE is 0" | ^~~~~~~
