internal compiler error: int i=40;my_t<char[i]> a;

[Klaus Wachtler <klaus at wachtler dot de>]

By mistake I wrote something like:
  int isize = 40;
  my_t<char[isize]> d;
I know it is not correct C++.
But i report it as a bug report since I got following compiler error:

Since my e2.cpp and the e2.ii don't differ (except the comments) I
copy the little e2.cpp directly into the text:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
// any template class:
template <class T> class my_t
{
  int value;
  T   anothervalue;
public:
  my_t(){};
  ~my_t(){};

  void set( int i ) { value = i; };
  int get() { return value; };
  void setanother( T i ) { anothervalue = i; };
  T getanother() { return anothervalue; };
};


int main( int nargs, char **args )
{
  my_t<int> a; // ok
  a.set( 25 );

  my_t<char[40]> b; // ok
  b.set( 30 );

  const int csize = 40; // ok
  my_t<char[csize]> c;
  c.set( 33 );

  // the following is nonsense; I know.
  // But it does not give an error "Klaus, this is nonsense on line...".
  // Instead it gives an "internal compiler error..."
  int isize = 40;
  my_t<char[isize]> d;
  d.set( 39 );

  return 0;
} /* main( int nargs, char **args ) */

Have a nice day!
