[Bug c++/23317] New: operator>>( istream&, int& ) does not work for enum values

["peter at gamelogic dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Assigning to an enum value from, for example, an istringstream fails, but the failure bit on the istream 
is not set.  Using an int temporary works just fine.

The .ii file is attached.  The output of g++ -v -save-temps Test.cpp is:
