I can't recreate the problem with your script (to compile successfully, I
removed -static from the command). All binaries were executed without problems
on corei7, with provided -march and -O2 flags. The binaries were linked with
glibc-2.16, though.

Please follow the instructions at [1] to provide a *minimized* runtime testcase
that exposes the failure, without dependencies on system libc.

BTW: From your report it is not clear if the problem is indeed in the compiler,
or in the system glibc.
