           Summary: infinite loop in g++
           Product: gcc
           Version: 3.2.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: matias at ssc dot upenn dot edu
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i386-redhat-linux
  GCC host triplet: i386-redhat-linux
GCC target triplet: i386-redhat-linux

When compiling the following code, g++ goes into an infinite loop. 

--- start of loop.cpp ------------------
class A {};

template <typename T>
class X : public A {
public:
  X(T&);
};

class B {
public:
  bool foo(A*);
  template <typename T>
  bool foo(T& t) { return foo(new X<T>(t)); }
};

int main()
{
  B x, y;
  x.foo(y);
}
--- end of loop.cpp ----------------

$ g++ -c loop.cpp
[never finishes]

Compiler version is:

$ g++ -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --enable-shared --enable-threads=posix
--disable-checking --with-system-zlib --enable-__cxa_atexit --host=i386-redhat-linux
Thread model: posix
gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)

Also verified the same behavior with g++ 3.3.1, compiled with the same configure
options.
