Hi,

   The following cryptic looking C++ code comes from page 309 of
Stroustrup and Lippman's ``Pointers to Class Members in C++'' article
from the USENIX C++ Conference, 1988.  It fails to compile on g++ 1.32.

Here's the code:
----------------------------------------
class X {
public:
   int i;
   void foo ( int ) {
   }
};

main ( int, char *argv [ ] ) {
   void (X::*pmfXVi2)(int) = &X::foo;
}
----------------------------------------

Here are the diagnostics:

----------------------------------------
In function main (int, char **):
bug.c:10: parse error before `*'
----------------------------------------

Note that if the declaration is moved to the outer scope ( i.e.,
outside of main() ) the compiler handles this correctly ( there seems
to be a general problem correctly parsing with this type of
declaration in both g++ and cfront 1.2.1. ).
