Summary: cc1plus hangs when compiling

Initial Comment:
After trying to compile one of old projects I ran into the situation when mingw32-g++ silently hanged up. After ah hour of research I refined the whole situation to this simple test file (evidently the main reason was the erratum; but it was better to have the compile error and crashed build here then to have three hours of senseless CPU torturing).

/////////////////////////////////////////
// test.cpp 
class A;

template <class T>
class B
{
  friend __attribute__((cdecl)) A& operator >>(A& a, B& b)
  {
    return a;
  }
};
//
/////////////////////////////////////////

Compiled with command:
mingw32-g++ -v test.cpp

Resulting output:

Using built-in specs.

Message:
The hang still happens with the latest sources. It also occurs in 4.6.1 in
64-bit Linux, so it is not MinGW specific.

Could you create a bug report on http://gcc.gnu.org/bugzilla ?

If you do, please tell us the gcc bug number afterwards so we can track its
progress.

Thanks,

Cesar

Message:
I confirm that this happens with 4.6.1 as well.  cc1plus.exe is clocking
CPU cycles with no I/O being registered as per the task manager.
