This bug looks similar to that one:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50882
There are a lot of open bugs in GCC :-(
IMHO this is not your fault.
In such a case, you can try to manually compile the offending file with the
exact same command line (copy/paste from the build log), but by decreasing
the optimization level (for example, -O1). Sometimes it works, then you can
continue to make normally.
And hence my question: has anyone successfully bootstrapped gcc-4.6.3 on
m68k?
I don't bootstrap, I only build a cross-compiler. Less trouble.
Anyway, the bug happens in libgcc, so the situation is the same since it is
built in any case.
I see that your problem comes from unwind-dw2.c. This is about DWARF2
exception unwinding. I didn't hit that bug because I use SJ/LJ exceptions
instead (due to lack of ELF support on my favorite platform).
The right solution would be to post a simplified, preprocessed test case in
GCC's Bugzilla. Unfortunately, GCC people does not seem to care much about
m68k issues :-(
Good luck.
