 [the first issues is fixed in 2.96, the second one remains - MvL]

 Hello,

 I've found a bug in gcc 2.95.2 that is not present in egcs-2.91.66.
 Here's some information about it. Feel free to e-mail me questions, if
 you have any.

 Bug summary:
 gcc 2.95.2 reports an internal compiler error if:
  - A class template declares itself as an unbound friend class template
  - The declaration is in a namespace

 The problem goes away if the unbound friend template class is not the
 class itself, or if the sorrounding namespace declaration is removed,
 such that the declaration appears in the global namespace.


 I've tried it on two separate installations, and the results are
 summarized below.

 Common for both test cases:

 Command:
   g++ -Wall -g -c tst.cpp


 Compiler output ( g++ -Wall -g -c tst.cpp ):
   tst.cpp:6: Internal compiler error.
   tst.cpp:6: Please submit a full bug report.
   tst.cpp:6: See
 <URL:http://www.gnu.org/software/gcc/faq.html#bugreport> for
 instructions.


 Source example:
   namespace nsn {

     template< class Type >
     class Test {
       template< class T2 >
       friend class Test ;
     };

   } // namespace 


 Test setups (Mandrake linux/gcc 2.95.2  and IRIX 6.5/gcc 2.95.2):


 Mandrake linux:
   gcc --version
   2.95.2

   uname -a
   Linux linux1.compile.sourceforge.net 2.2.14-mosix #6 SMP Mon Feb 7
 04:11:24 PST 2000 i686 unknown

 IRIX:
   gcc --version
   2.95.2

   uname -a
   IRIX64 alzheimer 6.5 07151432 IP27




 Incidently,

 class Test {
   template< class T2 >
   friend class Test ;
 };

 seems to generate an internal compiler error, regardless of whether it
 is declared in a namespace or not. I know it's bogus-code, but it still
 shouldn't cause an internal compiler error, right :-)

Release:
2.95.2

Unformatted:
  namespace
