David, can you have a look? Note, if I understand correctly *as* is
segfaulting, not the compiler!

AIX 5.3 has had many updates, so this bug report does not provide enough
information to know exactly which version of AIX as was used, not that I have
access to the exact version to reproduce it.  It works on my system.

aix 5.3   TL  11   and sp = 5 1036

Is there some specific level that it needs to be brought up to that will
correct the issue?

Not a GCC bug.

AIX 5.3 TL10 (as well as AIX 6.1 TL05 and AIX 7.1 TL00) instroduced AIX
assembler changes with some bugs.  An AIX iFix for AIX 5.3 is available (APAR
IZ98385 for AIX 5.3 TL10, APAR IZ98477 for AIX 5.3 TL11 and IZ98134 for AIX 5.3
TL12).  I know the assembler fixes address another bug with the assembler
generating corrupt object files, but I do not know if it fixes this bug of the
assembler crashing.

This is an AIX bug and you need to contact AIX Customer Support.

Thanks David for all of your insight and info.  I will forward this info to our
sysadmins to further investigate this assembler issue.
