>Description:
In a C++ program I have a function template that takes an
iterator as argument.  The program crashed and core dumped.
In trying to debug it, I went up the stack until I came
to the function template, and then I tried "print b[0]"
(b is an argument passed to the function; in this case it
is a vector<> iterator).  Gdb just spat out the error
message

Internal: Cannot demangle mangled name `__vc__Ct17__normal_iterator2ZPdZt6vector2ZdZt9allocator1ZdRCi'.


The program was compiled with gcc 2.95.2.

In general, I find that gdb falls apart when it comes to
any sort of template code or use of user-defined operators.
