This is an ICE that started with the recent r275745. The problem here is that
for a POSTINCREMENT_EXPR build_new_op_1 is called with null arg2, so arg2_type
is
also null after
5819 tree arg2_type = arg2 ? unlowered_expr_type (arg2) : NULL_TREE;
but then we make arg2 nonnull
5887 if (code == POSTINCREMENT_EXPR || code == POSTDECREMENT_EXPR)
5888 arg2 = integer_zero_node;
while arg2_type is still null and so
5940 else if (! arg2 || ! CLASS_TYPE_P (arg2_type))
crashes. Fixed by setting arg2_type in the ++/-- case.
Bootstrapped/regtested on x86_64-linux, ok for trunk?

PR c++/91819 - ICE with operator++ and enum.
* call.c (build_new_op_1): Set arg2_type.
* g++.dg/other/operator4.C: New test.
OK, thanks.
