[XLC++ 8.0] explicit instantiation requires well-formed default function
arguments
----------------------------------------------------------------------------------
Key: STDCXX-363
URL: https://issues.apache.org/jira/browse/STDCXX-363
Project: C++ Standard Library
Issue Type: Bug
Components: External
Environment: XLC++ 8.0
Reporter: Martin Sebor
I believe the program below is well-formed (according to 14.7.2, p9, an
explicit instantiation does not constitute a use of a default argument). It
fails to compile with XLC++ 8.0.
$ cat t.cpp && xlC -qversion && xlC -c t.cpp
template <class T> struct A { void foo (T = T::foobar ())
{ } };
struct B { };
template class A<B>;

"t.cpp", line 1.45: 1540-0063 (S) The text "T::foobar" is unexpected.
"t.cpp", line 3.16: 1540-0700 (I) The previous message was produced while
processing "struct A<B>".
