g++: Internal compiler error: program as got fatal signal 11

Since the Internal compiler error is caused by a segmentation violation
in the assembler, I think this PR is misassigned.
Testing the provided .ii file on UnixWare 2.1.3 worked as follows

2.91.66 19990314 with /usr/ccs/bin/as (CCS) 3.0 (u213_bl5)  worked.
2.95.3  20010315 with GNU as 2.8 worked.
3.0 20010521 (prerelease) - gave C++ errors.

Depending on the original gcc configuration, the problematic `as' could
be either UnixWare's or an older gas version. Upgrading either would seem
to fix the problem.
