[patch] PR 57362

[Sriraman Tallam]

Hi,

   http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57362

   This ICE reported here happens because the array storing the
function versions that should be processed is not indexed correctly.
This patch fixes this. This only happens when some versions cannot be
dispatched because a dispatcher for that is not available or is an
invalid target.


Is this alright?

Thanks,
Sri
