Description of Problem:

When I compile a sample program below
---- cut here ----
template <class T> class A {
  T *d;
  public: void f() { (T[10])d; }
---- cut here ----
the compiler fails by throwing Segmentation fault. 
The code itself does nothing, but as far as I know, 
it seems semantically ok. 
I can typecast pointer to an array, can I?

How Reproducible:

Steps to Reproduce:
1. compile the code.

Actual Results:
bugtest.cpp: In method `void A<T>::f ()':
bugtest.cpp:3: Internal error: Segmentation fault.

Expected Results:
Clean compilation or atleast more descriptive error message.

Additional Information:
Code compiles fine with IBM C++ for OS/2.

Seems to be fixed with http://gcc.gnu.org/ml/gcc-patches/2001-01/msg00941.html
which will appear in gcc-2.96-96.
