reproduction

found on private target, but can be easily reproduced on x86, so I think every
target is affected.

Compile attached file on gcc-4.7.2 with -O2 -DBROKEN to make function inlined.

Next run. You will see error. Compile just with -O2, next run and you will see
no error.

This error can not be reproduced on gcc-4.6.3, everything works fine. Problems
starts with 4.7
