Yep. Though it would be better to return a bad_p conversion than none
at all.
However, while playing
with some additional tests outside bug & testsuite (similar to
nullptr32.C), I noticed a latent issue: in case of base initializers we
were setting anyway LOOKUP_ONLYCONVERTING in add_function_candidate
Right. In the case of
+ TDerived()
+ : TBase<T>(nullptr) { }
we have direct-initialization of TBase<T>, but the parameter of the
TBase constructor is copy-initialized, so nullptr32.C is ill-formed;
please drop this hunk of the patch.
