No, this is not related to bug 58156. According to the current core language of
C++11, the code is indeed ambiguous.

There exists currently a core language issue to fix that, see

Hmm, but this example is still rejected in both GCC and clang (and MSVC) but
accepted for ICC. The example in both defect reports is done correctly with GCC
and all.
