That sounds possible.  The patch might indeed have the effect of
turning previously-silent miscompilations into ICEs.  I didn't expect
we'd get any, but you may be proving me wrong.  Would you please send
me the preprocessed testcase in private, or just confirm that you're
using newlib as the C library?  I'll then try to duplicate the problem
on one of the platforms at my disposal.
