OS: SunOS 4.1.1

The following program compiles with g++ 2.0 and g++ 1.37.1, but g++
2.2.2 receives fatal signal 11. This program was generated by yacc (!)
and then stripped down to the following:

-------------------------- Program -------------------------------
void yylex()
{
  int nstr;
  switch(nstr)
    {
      case 32: 
      case 33:
        ;
    }
}

yylook()
{
  int* c;
  int cc;

  for(;;)
    for (;;)  
        *c++ = cc = 
	( 1 ? cc : 0 ) == -1 ? 0 : cc ;
}

-------------------------- Compilation -------------------------------

-------------------------- Notes -------------------------------
Changing the order of function definition alleviates the problem. Also,
changing the `32' or `33' in the case statements to another number
alleviates the problem. Any simplification of the assignment to *c++
and cc in yylook() also alleviates the problem.
