I can't reproduce the problem on Fedora 14, x86_64.
I used bzr 104366 and the command:
~/src/gnu/emacs/trunkclone/src/emacs -q src/error.c
It could be a Fedora 15 thing, or it could be something else
different in our setups.
I recall having a similer problem on Ubuntu 10.10 that I tracked
down to a bug in the glibc string headers: they had marked memmove's
parameters to be 'restrict', which is quite bogus, and caused
GCC 4.6.0 to generate incorrect code. Are you using GCC 4.6.0?
Maybe you should look into those headers.
