Hi Fabian,
This is a gcc bug, as you guessed. So you need to report it on the gcc-bugs
mailing list. When you do, you might like to include the arm.c patch uploaded
here which will fix the problem(*).
Gas should not be generating an internal error however, even when given bad
assembler input, so I have applied a small patch to replace the assertion with
an error message.
Cheers
Nick
PS. FYI I was not able to reproduce the bug using the assembler file that you
uploaded but I was able to reproduce it when building a toolchain with the
configuration options you specified. I was also able to capture the gas
command line and assembler input by adding "--save-temps -v" to the gcc command
line.
(*) After applying the patches in this PR I tried continuing the build. It
failed with:
libstdc++-v3/libsupc++/eh_throw.cc: In function 'void
__cxxabiv1::__cxa_throw(void*, std::type_info*, void (*)(void*))':
/work/sources/gcc/current/libstdc++-v3/libsupc++/eh_throw.cc:80:57: error:

I suspect that setjmp/longjmp exception handling support may have bit-rotted.
At least for the ARM anyway.
