[Chicken-users] Fix for Segfault - a hard one

[F. Wittenberger]

Hi all,

is it ok to do a wild guess?

thread-terminate! looks suspicious here in comparsion to other uses of
thread's slot #2:

$ svn diff srfi-18.scm 
Index: srfi-18.scm

   (when (eq? thread ##sys#primordial-thread)
     ((##sys#exit-handler)) )
-  (##sys#setislot thread 2 (list (##core#undefined)))
+  (##sys#setslot thread 2 (list (##core#undefined)))

'(terminated-thread-exception) '()))
   (##sys#thread-kill! thread 'terminated)
   (when (eq? thread ##sys#current-thread) (##sys#schedule)) )

I patched it as above and the testcases I posted yesterday and the day
before are working now in my environment.

Am I correct, that setislot will set immediate values, while a list
clearly in not?

Best regards
