Core Dump

PostgreSQL just quit on me unexpectedly for the first time ever.  I have no doubt I did something stupid to cause it,
butI can't find any clues in error logs.  Here is a backtrace of the core file, I am wondering if it tells anyone
anything.

I hacked my pltcl.so the other day, but all has been well up to now.  I added a few SPI_freetuptable() to keep pltcl
fromhogging all the memory.  I wonder if I hacked it a little wrong. 

                             version
