That's the Linux GCC. You will want to see the version for MinGW: mingw-gcc-9.2.1-6.fc32 - which does not crash so I'm not surprised you didn't crash. > Michael: is that the mock configuration that's failing for you, or are you > using a different one? Try: mock --rebuild mingw-wine-gecko-2.47.1-2.fc32.src.rpm -N -r fedora-33-i386 It's still failing for me today. I'm working around it by passing -save-temps to CFLAGS as packages that fail to compile in Fedora for too long are dropped from the distribution.
