--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Shorter testcase (for -std=c++14 and later, at least for C++98 I think it is
correctly ambiguous):
typedef decltype(sizeof 0) size_t;
void foo (int);
void foo (const char *);
void
bar ()
{
foo (size_t (0));
}
I think the problem is that convert_to_integer_maybe_fold will ignore the
dofold argument if the expression is constant.
So, shall we punt on folding that, or just punt on folding it in the
problematic case (possibly wrapped 0 constant), something else?
