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
