Description Takeshi Watanabe 2011-05-09 14:01:18 UTC 
I got the following error:

gcc-enum-class-test.cxx:9:7: internal compiler error: in constructor_name_p, at cp/name-lookup.c:1862
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

compiling the attached code.
I don't know much about c++0x but I think that should be an error.

  ENUM::Type func() { return ENUM::a; }
