Does anyone know whether the developers for the Debian m68k port have
run into an issue while compiling gcc (beginning around gcc-12), as documented at this link:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109927

If you are not seeing any issues, then you might be using a set of
options or patches that could be useful for the Gentoo developers.

We don't have any specific patches but we're building our packages using qemu-user and not qemu-system which is why we aren't running into memory constraints that quickly.

For what is worth, you should use the "virt" flavor when running qemu-m68k instead of the Quadra 800 flavor as this way you have more memory available.

See this video by Laurent Vivier created the "virt" target for m68k:

Thanks, it's good to know it's not happening with qemu-user.

Here is the latest build log btw:

https://buildd.debian.org/status/fetch.php?pkg=gcc-13&arch=m68k&ver=13.1.0-3&stamp=1684690928&raw=0

I am using the virt m68k VM.

OK. The only other project that comes to my mind where you run into memory exhaustion issue with qemu-system is the GHC Haskell compiler. Building it
on qemu-user works fine there, too.

Were those Debian qemu-user builds ever attempted on a 32-bit host?
