Hi

This was initially reported at
https://bugs.launchpad.net/ubuntu/+source/gcc-4.6-armel-cross/+bug/827990 and
Michael Hope produced a reduced testcase which is confirmed to affect GCC
4.6.1.

Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.6/README.Bugs> for instructions.

Michael Hope also notes:
"Note the use of -fno-builtin to suppress a warning.

The fault occurs at -Os, -O1, -O2, and -O3. The work-around is to compile at
-O0."

(I'm attaching his reduced test case, the original files are in the Launchpad
bug in the unlikely case you'd need them)

Bye,
