Possibly it's time to look at the malloc() on your machine.  A bad malloc()
can do very strange things at completely unpredictable times.  Try using 
sdb to find the exact point at which it crashes.  If the crash occurred 
while trying to allocate through a pointer look very closely at the 
pointer value.  Make sure it is not odd.  Also make sure the value is
divisible by four.

I have it compiled on a sequent balance running 4.3bsd.  At first it
wouldn't compile for seemingly no reason.  I kept getting syntax errors
associated with the variable "private", which you'll find correctly
declared in the TILE code.  Then I discovered some fool had hardwired 
"private" into the C compiler as a reserved word, presumably to mean the
same as static.  If you're getting wrongly defined variables that could
be the reason.
