I should have added that my problem has nothing to do with the recent
thread on "garbage collector infloop in 21.4.9 and 21.5beta4 on MacOS
10.2". It is *not* a stacksize problem. I have set the stacksize to 8192
and even to its maximum of 65536 kbytes, without any effect.
And, although my problem seems to appear in a garbage collection
routine, too, it was not present in 21.5.b4 which builds correctly. It
must be caused by something introduced between beta4 and beta9.
