	Yes, I have noticed similar.
	Debugging it has turned out to be most difficult
	in deed...

	I will try to dump a  libmalloc_d.a  using version
	for testers -- my own copy of it crashes on memory
	test mode quite quickly in deed..  (Without the test
	mode I am not yet sure if it will live thru a message.
	I just got the  libmalloc_d  compiling on Solaris;
	It had troubles with various odd interdependencies,
	and name collisions(!) with Solaris libraries.)

	There is a memory corruption somewhere..

	Also the  scheduler  seems to suffer from it, or
	then the   libmalloc()  is broken.  Investigation
	continues.

(Deleted an interesting example showing the crash by redoing
 "router LISTNAME" several times in a row. N:th invocation
 crashes.. -- list containing a bunch of addresses, mostly
 local ones.)
