Insight core dumps on failed Tcl_Alloc

Hello.
I have been running into strange problems with insight core
dumping while attempting to allocate memory. These seem to
happen randomly. I am running a RedHat 5.2 (Intel) Linux
system with the 19991011 build of insight. In the hope that
it might help, I have attached the stack trace I got
from insight when it crashed.
Has anyone else run into this problem?
Thanks
Mo DeJong
