Hi,

The testcase at https://launchpadlibrarian.net/128616769/compare-test.c

With aarch64:

aarch64-oe-linux-gcc -o a-test ./compare-test.c ./a-test: fail ret: -1: Bad address

With X86_64:

gcc -o test ./compare-test.c ./test correct. ret: -1: Bad address

setting -D_FILE_OFFSET_BITS=64 doesn't make a difference.

This is with:

gcc version 4.7.3 20121205 (prerelease) (Linaro GCC 4.7-2012.12)

This was found while debugging:
