 Hi,
 
 the bug can be reproduced with an even simpler example:
 
 struct A
 {
     A(A&);
     template <class T> A(T);
 };
 
 A a = 0;
 
 The compiler (g++ -c) seems to run into an endless loop which is killed
 by the system when all virtual memory is exhausted. This affects gcc
 3.0.x and the main trunk (gcc 3.1 as of 20011231) under i686-pc-linux-gnu.
 However, gcc 2.95.2 does not have this problem.
 
 See also http://gcc.gnu.org/ml/gcc-bugs/2002-01/msg00202.html
 which is probably related.
 
 Greetings,
 Volker Reichelt

>Description:
A few templates using each other cause g++ to do a "segmentation fault". I guess my code itself has a flaw, just the way the compiler tells this is not very helpful.

I am attaching the source file. It's 13 lines and no include file.
