[Bug c++/15050] New: Compiled templated code crashes on delete []

[bracken at ansoft dot com]

I can compile the attached (simple) source file without warnings, but when I 
attempt to run it, it crashes at line 92 (delete [] mData.)  The thing I'm 
attempting to delete is a pointer to a base class.  The pointer is actually 
pointing to an array of objects of a derived class.  The base class has a 
virtual destructor and the derived classes implement their own destructors.  
The base and derived classes are templated.

I've observed this in g++ 3.1, 3.2 and 3.3.2 on RedHat Linux 8, HPUX 11 and 
Solaris 7.  It does not happen if I build with Sun Forte, HP's aCC, or 
Microsoft Visual C++.

To build the program:

g++ -o delcrash delcrash.cxx

Here is the output of gcc -v:

idea(4): gcc -v

Thread model: posix
gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)

If possible I would appreciate a 3.2 compatible fix since I'm stuck with 3rd 
party libraries built around 3.2.
