[Bug c++/19762] New: [3.4/4.0 regression] ICE in invalid explicit instantiation of a destructor

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following invalid code snippet causes an ICE since gcc 3.4.0:

======================================
template<int> struct A { ~A(){} };
template A<>::~A();
======================================

The error message is:

bug.cc:2: error: wrong number of template arguments (0, should be 1)
bug.cc:1: error: provided for 'template<int <anonymous> > struct A'
bug.cc:2: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in constructor_name_full, at cp/name-lookup.c:1662
Please submit a full bug report, [etc.]
