 Matteo, does it happen with a smaller region?

 toReceive.type is from the r.li.daemon, and is declared as "int" in the
 msg struct in ipc.h. But it should only be a #defined constant 1-5, so I
 would rather guess that the stack is being smashed.

 note in devbr6 (6.5svn) it respects the WORKERS=1 environment variable for
 easier debugging. there should be control for that in trunk too, but the
 multi-processor part has been rewritten there so controlling the number of
 jobs is probably a bit different.

 ps- 'g.region -a res=0:00:10' might be nice to clean up the region
 settings

 pps- if you take ownership of a bug (ie declare responsibility for fixing
 it) please manually add the mailing list in the cc field so the discussion
 gets echoed there.
