The following invalid code snippet triggers an ICE on mainline:
===========================
bool b = --0i == 0;
===========================
bug.cc:1: error: lvalue required as decrement operand
bug.cc:1: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in fold_comparison, at fold-const.c:8459
Please submit a full bug report, [etc.]
