I couldn't repro with fresh trunk on x86_64-apple-darwin12.5.0 and
x86_64-unknown-linux-gnu.

I don't have an access to a darwin box, so I can't even try to reproduce it.

The ICE is gone for me (trunk revision 217694 with patch at
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63534#c50), and testcase
Wsizeof-pointer-memaccess1.c now passes. Thus probably IPA related, and now
fixed.
