Created attachment 650602 [details] build.log.xz Got this at trying to build gcc-9.3.0-r1 on my G4 DP. Tried to build a 2nd time and got exactly the same error. I tried to work through https://wiki.gentoo.org/wiki/Gcc-ICE-reporting-guide but failed to replicate the command as I only got "/var/tmp/portage/sys-devel/gcc-9.3.0-r1/work/gcc-9.3.0/gcc/ggc-page.c:20:10: fatal error: config.h: No such file or directory" executing the command out from /var/tmp/portage/sys-devel/gcc-9.3.0-r1/work/build.

if you're hitting this with a modern GCC (e.g. 9.4.0, but ideally a newer branch), let us know?
(In reply to Sam James from comment #2) > if you're hitting this with a modern GCC (e.g. 9.4.0, but ideally a newer > branch), let us know? Didn't encounter gcc build problems meanwhile on ppc. Atm I am chasing a kernel bug which happens during longer builds (https://bugzilla.kernel.org/show_bug.cgi?id=215389). Building/testing gcc natively on the G4 makes sense again, if anything, when this one gets fixed.
