Subject: glibc double-free error
Date: Mon, 01 Jan 2007 17:29:30 -0800

I'm using pg_dump/pg_restore to quickly copy databases between servers.  But my server keeps crashing when I run pg_restore:

    glibc detected *** double free or corruption (!prev): 0x0a00b1a0

Postgres: 8.1.4
   Linux: 2.6.12-1.1381_FC3
   glibc: 2.3.6-0.fc3.1

Server: Dell
   CPU: Xeon 2.80GHz
Memory: 4 GB

This is pretty repeatable.  Any particular pg_dump file that causes the crash will cause it every time it is used, and it happens with a lot of my databases.

What can I do to help diagnose this problem?

Craig
