Thanks for the report. I actually made a nasty mistake in the last
patch after code refactoring, which is to not properly check that
a QueryDesc is already being tracked. So every subquery call
in the same query is allocating DSAs and those segments are not
being properly cleared. So the patch is broken and probably explains
your crashes.
Just made a 1 line fix and make installcheck looks clean now. Will
do more tests before sending another version.
