Hi
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
I havent figured out the commit yet. Should you need a bug in linaro bug tracker I will be happy to file one
Thanks -Khem

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.)

Yes, please do so; this makes it easier to track the problem on the Linaro side. Thanks!
Mit freundlichen Gruessen / Best Regards

same for the Ubuntu side. If you see this in one of the gcc-4.x packages in Ubuntu, please open a task for the corresponding package in Ubuntu.
thanks, Matthias
