Our g++ 1.33 gets signal 6 on Sun 3, Sun 4, and HP when it encounters some kind
of redefined classes. Here is the minimum code we found to trigger the bug :

class STRING {
public :
        STRING (char*);
        STRING (int);
        STRING (STRING&);
};

class STRING {
public :
        STRING (char*);
        STRING (int);           // no error at all when suppressed
};


hp2-> g++ -v -c String.cc
g++ version 1.33.0

The message is slightly different when cross-compiling on a Sparc :

g++ -v String.cc

Failed assertion at  __LINE__ 766 of `tree.c'.
g++: Program c++ got fatal signal 6.


While trying to reduce that code, we discovered that g++ finds no error
when the second constructor of the second class is not there.

Hope that will help ...
