Comment:

 @vshabanov: thanks very much for the core dump.  I poked around in it and
 did manage to find a bug in the RTS, the fix for which I have just
 committed (see above).  I don't know whether this is the only bug, but it
 is certainly ''a'' bug.

 We'll close the ticket after the patch has been merged, on the optimistic
 assumption that the bug is fixed.  Please try again with the 7.4.2 release
 candidate if possible, and re-open the ticket if you still have problems.
 Thanks again for the report.
