Hi,
8.4.3 is crashing for me under load, below is the stack trace:

The bug is reproducible, I'm not sure how to proceed. Here is the output
from the log:
LOG: server process (PID 8886) was terminated by signal 11: Segmentation
fault
LOG: terminating any other active server processes
WARNING: terminating connection because of crash of another server process
I have been seeing these messages:
LOG: autovacuum: found orphan temp table "pg_temp_7"."found_sizes" in
database "gb_render_footwear_db"
LOG: autovacuum: found orphan temp table "pg_temp_7"."classification_tree"
in database "gb_render_footwear_db"
Could they be the result of previous crashes? Any help is greatly
appreciated.
All of this code ran perfectly under 8.3.
Thanks,
Rusty
