Definitely the wrong version of the patch. It's missing the
INTEGRAL_TYPE_P test that was added to fix this exact problem.
This is the delta to get to the version that should have been checked in.
* tree-ssa-dom.c (record_equivalences_from_incoming_edge): Add missing
check for INTEGRAL_TYPE_P that was missing due to checking in wrong
version of prior patch.
