[Openmcl-devel] openmcl quits without backtrace

I work mostly in MCL, but often I switch to OpenMCL to track down  
bugs and/or to note efficiency issues.   I've seen a strange error in  
MCL with respect to this form/closure:

(let ((copy-htable (make-hash-table #+Ignore :rehash-size #+Ignore  
1.5)))
   (defmethod copy-top-level (ORIGINAL-THING)
     (clrhash COPY-HTABLE)
     (copy-one ORIGINAL-THING COPY-HTABLE)))

This is part of the library that my group uses.  The trouble is that  
the copy-htable is getting smashed by something - probably GC.  This  
error occurs after ~18 hrs of computation.  So I fired up OpenMCL to  
see if I could reproduce the error there.  It takes only 10 minutes  
for OpenMCL to crash and it does so without errors or a backtrace -  
the process just dies.  I have no idea whether the two problems are  
related, but I usually have little (to no) trouble running the  
offending code (and other code) in OpenMCL.

Any suggestions on why OpenMCL would crash in such a way?
