Postgres Crash Running PLPGSQL Function on 8.2.3

Has anyone experienced any problems with the Postgres 8.2.x database
crashing when running PLPGSQL functions?

When I try to run my plpgsql function it causes Postgres to restart
unexpectedly. The code was working with prior versions of Postgres,
now it seems to be crashing the postmaster. Here are my log entries...

2007-03-27 10:20:35 LOG: statement:

SELECT "2007-3".getopencharge('822512', '2007-3-31',

When I run the function, it runs ok the first time. The second time
right after that, the crash occurs. This is consistent every time I
run this test.

This problem seems to be exactly the same symptoms as a bug I reported
already #3158/#3166, but have not seen much dialogue on it. I am not
sure how to correct this problem as it was already working fine in a
prior version of Postgres.

I am running this on a Windows 2003 Standard Server SP1. The server is
an Intel P4 XEON with 1GB RAM and Ultra 320 RAID 10 Configuration. My
PostgresSQL version is 8.2.3.

Can any one help with this?
