Classification: Unclassified

The code causing the failure
An ICE occurs in a constexpr constructor where a member is initialized that is
in an anonymous member union containing an anonymous struct. See attached file.
Compiling with g++ -std=c++11 -c tes.cc yields:
tes.cc: In function 'int main()':
tes.cc:23:21: in constexpr expansion of 'r.CRect::CRect(1, 2, 3, 4)'
tes.cc:23:21: internal compiler error: in base_field_constructor_elt, at
cp/semantics.c:7033
