Hi Alex,

Ah ha - difficult to reproduce but yes I now get:

   foo.s: Assembler messages:
   foo.s:1: Fatal error: failed sanity check

Note - this bug does not seem to have stopped me from building gcc with 
the mainline sources, but then I am not configuring with glibc in the 
same way as you and there are probably some other differences in our 
build environments as well.

I assume however that this must be a gcc bug - ie it has miscompiled 
gas.  Have you investigated further yet ?

Cheers
   Nick
