In nmeter.s.gcc4, I see that collect_mem saves/restores %ebx. Fishy.

Can you step through the above fragment in gdb and confirm that %ebx gets
clobbered? If yes, which collect_XXX func does that?

It is seems gcc bug.

When gcc built on x86_64 machine, even on chrooted 32-bit environment, it
seems have some bugs, until i set also setarch i686 (by personality
syscalls) and rebuilt gcc. 
Even it is building 32-bit binaries by default, it is broken. I think it
is kind of difficult will be to report such bug to gcc bugzilla? Is it
worth it?

Btw i face such bug only once, with nmeter.
You can just close bug, if it is not interesting for you anymore.
