We were ICEing on the attached testcase, because in check_narrowing,
for = {{}}, we wanted to check recursively the CONSTRUCTOR_ELTs,
even though init in this case has 0 CONSTRUCTOR_NELTS. So I added
the check for CONSTRUCTOR_NELTS > 0. Moreover, since empty scalar
initializers are forbidden in C FE, I think we should error out here
too. (Complex type is considered as an arithmetic type as a GNU
extension and arithmetic types are scalar types.)
Empty scalar initializers are allowed in C++11, so we shouldn't give an
error. Your initial patch from bugzilla is OK, with an appropriately
adjusted testcase.
