I've been trying for at least two weeks to make an m68k-coff cross
assembler under linux, but have been getting this:
[aaron@aaron2 src]$ as -v --bitwise-or -k --register-prefix-optional -ovideo.o video.s
GNU assembler version 2.9.1 (m68k-coff)
Segmentation fault (core dumped)
[aaron@aaron2 src]$ gdb `type -path as`
GNU gdb 4.17.0.11 with Linux support
[...]

so when I saw that binutils was actively being hacked on again, I
figured I'd give it a try, but gas coredumps yet again, but in a
different place. (This is with binutils-2.9.4.0.4)

All binutils have been configured with:
../configure --target=m68k-coff --enable-shared \
--prefix=/usr/local/cross --exec-prefix=/usr/local/cross \
--enable-targets=m68k-ieee
It's strange because if there are errors in the source, the assembler
dutifully reports them without segfaulting.
