I seem to be having problems with void ** and the stack.  A friend has
problems with void * which are similar.  Here's some example code:


unsigned long	symbol;
char		*word;

functionA(word, &symbol)
}

functionA(char *w, unsigned long *symbol)
{

functionB(&symbol);

/* value of symbol is garbage */
}

functionB(void **symbol)
{
unsigned long	*s;

*s = 5;

memmove(*symbol, s, sizeof(unsigned long));
}

Something like the above.  When we get to the above comment, the value
of symbol is garbage.  Strange thing is that this isn't ALWAYS true.
Sometimes it works, sometimes it doesn't.  Most times it does.
Clearly there's a problem with the void ** or void * type.
