When building moonjit as a package for openSUSE, it failed on PPC64 (that’s Big Endian):

Complete build log with all details

It is moonjit 2.2.0 from the tarball from GitHub together with the patch from #105.

commented

That's a gcc bug; it's an internal compiler error in gcc. See also #74.

commented

I just noticed that the previous report was also from an OpenSUSE build. Perhaps the builders need to be updated to fix the gcc bug.

commented

OK, according to our GCC people, it is gcc bug, but a new one, https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94420 (the other one you pointed out was really solved many years ago).

commented

Thanks for getting this reduced and reported. I'll close this once you confirm that the patch in the bz fixes your build.
