>Description:
If a static const member of type pointer to member is initialized in cla
ss, and the initializer is a template argument, gcc-3.2 exits with a segmentatio
n fault.
The full compiler output is as follows:

 c++ -Wall -c -o nocompile.o nocompile.ii
 gccbug.1.cpp: In instantiation of `B<&A::dummy>':
 gccbug.1.cpp:21:   instantiated from here
 gccbug.1.cpp:11: internal error: Segmentation fault
 Please submit a full bug report,
 with preprocessed source if appropriate.
 See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

Gcc-2.95.3 compiles such a construct fine.

(This report is just like PR8152, which somehow missed the file attachment. I am sorry for that.)
>How-To-Repeat:
compiling of the attached preprocessor output (c++ -Wall -c nocompile.ii).
>Fix:
A non in-class initialization is accepted. 
I.e. :
-------------------------------
 class A;
 
 template<int A::* P>
 class B
 {
 public:
 
 static int A::* const p;
 };
 
 template<int A::* P>
 int A::* const B<P>::p = P;
 
 class A
 {
 public:
 
 int dummy;
 B<&A::dummy> d;
 };
--------------------------------
compiles just fine.
