Hopefully fixed below. Thanks for watching.
gcc/cp/
* semantics.c (cp_parser_ctor_initializer_opt_and_function_body):
Set the pointer to the last block of the constructor to the
current statement.
(build_constexpr_constructor_member_initializers): Get
build_data_member_initialization a chance to deal with more
statements before we choke.
gcc/testsuite/
* g++.dg/cpp0x/constexpr-diag4.C: New test.
