[Bug c++/34774] New: templates, enumerations, overflow, ice

["tbptbp at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

While trying to pinpoint an *intermitent* warning/error with g++ 4.3
"mf/unit.h:84: error: no integral type can represent all of the enumerator
values for `metafloat::core::helpers::details::aligner<7u,
metafloat::core::float_t<0l, 0l, 0ul,  CAT_NRM> >::<anonymous enum>'" i finally
got it to ice with the attached version. Even better, the venerable g++ 3.4 as
shipped by Cygwin also craps out.
