>Description:
----- stl.cpp -----
#include <list>

int main()
{
  std::list<int> l;
  l.push_back(1);
}
----- stl.cpp -----

(gdb) b main
Breakpoint 1 at 0x80497b1: file stl.cpp, line 5.
(gdb) run
Breakpoint 1, main () at stl.cpp:5
5         std::list<int> l;
(gdb) whatis int
type = int
(gdb) whatis int*
type = int *
(gdb) whatis std::list<int,std::allocator<int> >
type = std::list<int, std::allocator<int> >
(gdb) whatis std::list<int,std::allocator<int> > *
A syntax error in expression, near `'.
(gdb) whatis 'std::list<int,std::allocator<int> > *'
No symbol "std::list<int,std::allocator<int> > *" in current context.

GDB can understand pointer to int, but there's no way to understand a pointer to std::list.

  This looks like a bug in GDB, in the c-exp.y parser.
