--- Comment #1 from Sanjay Patel <spatel+llvm at rotateright.com> ---
I think the source program encounters undefined behavior because:

Feel free to reopen if you disagree.

This is a long-standing problem for clang as you can see from that bug report
and related/duplicates. 

Work is ongoing to support an FP environment that includes exceptions. You can
check status of that on the llvm-dev mailing list.
