------- Comment #12 from rguenth at gcc dot gnu dot org  2007-09-23 12:40 -------
This sounds like possibly an aliasing issue.  Anyway, does this still occur
with a maintained version of GCC?  That would be at least 4.2.1.

Not a bug in the C front end.  The next step in tracking down the problem would
be to try compiling just one file with -O2, the rest with -O0, and find which
file being compiled with -O2 yields the problem.  Then split out the functions
from that file into separate files and see which function is being miscompiled.
