Hi,
We support SQLite for data storage in Prosody, an XMPP server.
Recently someone reported a number of crashes happening in SQLite on
their server: http://prosody.im/bugs/269
The first 2 crashes both happen on the same line:
pParse->pZombieTab = p->pNextZombie;
The code that assigns pZombieTab has a comment referring to ticket
#3346, which may or may not be relevant.
A third crash happens in closeAllCursors: http://prosody.im/bugs/269#c4
for(pFrame=p->pFrame; pFrame->pParent; pFrame=pFrame->pParent);
The SQLite version is 3.7.3-1 in Debian stable. I have built the
Debian source package myself so I could correlate line numbers with
the stack traces. The resulting sqlite3.c file is here:

Prosody is using a 3rd party database library for Lua (LuaDBI). If the
fault lies there I'm happy to fix it, but right now I don't know where
to start looking. Does anyone have any ideas on what could cause this
kind of behaviour?
Many thanks,
Matthew
