--- Comment #8 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
I think the original testcase and the reduced testcase point out to different
issues.  The issue with the testcase in comment 1 is that we don't reject the
user-provided definition of std::initializer_list (it has a pointer followed by
an integer field), but convert_like_real assumes that the second integer field
has a size_type, which might not be true, here my fix helps.  I don't know yet
the cause of the ICE with the unreduced testcase.
It might make sense to fix these separately.
