--- Comment #6 from Jeffrey A. Law <law at redhat dot com> ---
Note there's a load of a[400] that would be an out-of-bounds array access if
that load were to be executed.

Perhaps something is causing that load to execute and the result ignored/thrown
away (if-conversion?).

If someone is able to reproduce this bug, please attach the executable, .s and
.o files so that we can dig deeper into this problem.
