[Bug c++/19884] New: [3.3/3.4/4.0 regression] ICE on explicit instantiation of a non-template constructor

[reichelt at gcc dot gnu dot org]

The following code snippet causes an ICE since gcc 3.3:

==========================
struct A;
template A<>::A();
==========================

ctor.cc:2: error: 'A' is not a template
ctor.cc:2: error: explicit qualification in declaration of `A A()'
ctor.cc:2: internal compiler error: in lookup_template_function, at cp/pt.c:4245
Please submit a full bug report, [etc.]

This is similar to PR 19764 (only with the constructor instead of the
destructor), but the failure is in a different position and it's not fixed
in mainline.
