gcc5-pr64809.patch

IMHO in any case we should apply something like the attached patch, there is no
point to even look at the debug stmts and TER really shouldn't make any
guarantees for uses in debug stmts, those must be by definition ignored for TER
purposes.  Whether that is sufficient is another question.
