SuSE 7.3; uname -a:
Linux armageddon 2.4.16-4GB #1 Tue Dec 18 15:56:11 GMT 2001 i686 unknown
Configured with: ./configure --prefix=/opt/gcc3 --enable-shared --enable-threads --enable-cpp --enable-languages=c++,f77
Thread model: posix
gcc version 3.0.2
The following piece of code (something like that was entered
by mistake) causes gcc3.0.2 to eat up all available memory
and crash ("gcc3crash.cpp"):

struct A {
        A(A& v) {}
        template<class T> A(T x) {}

void test()
        A x = 12;

if you change A(A& v) to A(const A& v) (so it becomes
a normal copy constructor) the code compiles ok.

g++ -c gcc3crash.cpp
don't know how to fix it
