So I haven't been ignoring this report, but I cannot reproduce
it on the SB2500 I have access to right now.
I've been doing gcc builds and testsuite runs in a loop for
several days.
Occaisionally I get a dying 'as' which I have seen before and
plan to investigate, but no hard hangs and no crashes.
I'll keep prodding, but if you can narrow it down further
please let us know.
