The bug http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46883 files against GCC trunk also happens with linaro gcc 4.5 My guess is that there is a backported patch from trunk into linaro 4.5 tree thats causing this ICE

This ICE does not happen on upstream gcc-4.5 branch

Thanks for the bug report!

I havent figured out the commit yet.

It looks like the regression was introduced by Bernd Schmidt's patch to improve zero-/sign-extensions (PR 42172), which we did indeed backport to Linaro GCC 4.5. (I've updated the PR 46883 bugzilla with more details.)

Should you need a bug in linaro bug tracker I will be happy to file one

Yes, please do so; this makes it easier to track the problem on the Linaro side. Thanks!

Mit freundlichen Gruessen / Best Regards
