[Bug c++/38640] New: ICE with decltype of template value parameter

[reichelt at gcc dot gnu dot org]

The following valid code snippet triggers an ICE since GCC 4.3.0
(when __decltype was introduced):

================================================
template<int N> void foo(__decltype(N));
================================================

bug.cc:1: internal compiler error: in finish_decltype_type, at

This is a regression as we went from rejecting this code to ICEing on it. 

Confirmed.
