gfaults at argp-help.c
It has been like that for about two weeks. This machine attempts to compile
gcc-svn and glibc daily. Sometimes it works sometimes not.
I tested with glibc 2.9 and gcc appears to still segfault.

Since this is an inline-asm, it gets processed by the assembler and not GCC.

Confirmed with the reduced testcase only, at -O2 -Wall. The warning happens
after PTA triggered by SRA.
Relevant constraints:
__y_7 = &s.64+64

and code:
D.2839_21 = &__y_

Oops, typo: I meant the bug is triggered with "-O3 -Wall".
The reduced testcase already triggers the warning with "-O2 -Wall" thanks to
some additional "inline"s.
