Thanks for looking into this!

Yeah, 3.0.4 is a very early version for m68k (after the m68k backend got
revived), and the 3.0.4 was maybe the first ever version which really
worked on Linux-m68k. So I was actually kinda surprised it even worked to
that level, so it could be included in Debian... :) I would avoid fighting
with that if possible.

I cross-built a recent 3.2.1 compiler from our fixes_3_2 branch (this will
be released as 3.2.2, eventually), I uploaded it here:

Can you try bootstrapping with this compiler binary? At least from FPC's
perspective, you shouldn't need anything else, to initiate a cross build
than a bootstrap compiler binary, and GNU binutils and make. Not sure if
Debian needs anything else.

If this also crashes, then I have to dig deeper to identify the problem,
because 3.2.x will be with us for a while, and I'd like it to be built for
Debian-m68k.

Cheers,
