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.)
