I will check, but it takes some time as I deleted it already.

Can you upload the console contents (just the last "block" would be enough) and maybe try finding the relevant .log file somewhere inside the build directory?

Though 12.1.0 build completes, the big-endian patch I applied does not work. I will try 12.2.0 when this patch works.
Edit:
Ran build again, now the patch works.

Here now the compile which fails for 12.2.0

Just to note: Linux and cross-win64 build on WSL2 works.

If is not always the same line which throws the segmentation fault. Succesive runs stop at different places.

Compiling GCC with -O0 prevents the crash. I will try if -O1 or -Os work.
Only need to find a way how build-....sh can feed this into the GCC makefile.

Building gcc-final with
CFLAGS=-O1 CXXFLAGS=-O1
fixes the segmentation fault issue.

One more thing you could also try is changing nproc="$(sysctl -n hw.ncpu)" to just nproc=1. If only the optimization helps, then I guess it must be some upstream GCC bug - either in the toolchain on your PC or in the GCC source that is compiled.

I give it a try.

I tried it. -j 1 does not help. 12.2.0 and 12.3.0 need -O1 for CFLAGS/CXXFLAGS when building gcc on MacOS. Could be an XCode problem.
But it does not matter much. The M1 Mac is blasting quick and my main development machine is a PC (Windows/WSL2) so I do not care if -O1 or -O2 for the tools.
