Unfortunately we call into the middle-ends invert_truthvalue right in
cp/typeck.c:build_unary_op as we build the TRUTH_NOT_EXPR, so at the
time we
reach the gimplifier we already crashed.
In that case, I think we should fix the middle end to handle this case;
it's not a very major change to the semantics of GIMPLE/GENERIC to
handle this case. (I'm assuming that aren't massive ripple effects
throughout the middle-end...)
Mark did you look how long this bug as been here, it predates tree-ssa
by a year. So I don't think we should change TRUTH_NOT_EXPR/COND_EXPR
semantics. The C++ front-end needs just stop doing bad stuff like this.
