[Bug c++/14122] New: problem with non-type tmplt parm in member template

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

g++ gives an error compiling the source given below.

$ g++ -c x.cc
x.cc: In instantiation of `A<(&str)>':
x.cc:9:   instantiated from here
x.cc:6: error: could not convert template argument `&str' to `const char*'
x.cc:6: error: could not convert template argument `&str' to `const char*'
x.cc:6: error: could not convert template argument `&str' to `const char*'
$

While i don't have a language reference handy at the moment, i don't
see anything wrong with the code.  Further, gcc accepted it through
at least the beginning of January.

Oddly, the error goes away if the `const' qualifier on `str' is removed.

Environment:
System: Linux karma 2.6.1 #10 Tue Feb 10 04:31:35 EST 2004 i686 i686 i386 GNU/Linux
Architecture: i686

	<machine, os, target, libraries (multiple lines)>
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc/configure --prefix=/usr/local/gcc --enable-threads=posix --enable-long-long --enable-languages=c,c++,f77

How-To-Repeat:

Compile the following:

-----------------------------------------
extern const char str[];

template <const char* P>
struct A
{
  template <const char* R>  void foo();
};

template class A<str>;
-----------------------------------------
