Yes, and with -save-temps you double the disk space required. :(

That's a reasonable mock command for a Fedora 32 build.

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.

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-tem=
ps
to CFLAGS as packages that fail to compile in Fedora for too long are dropp=
ed
from the distribution.=
