[lxml-dev] Crash on Win32 under heavy stress

[Stefan Behnel]

Hi Sidnei,

I'll be away on vacation starting today, so I regret I can't provide too much
critical help at the moment.

So, just a quick note here.

For a quick test, try with 1.3beta or the current trunk. No guarantee, though,
especially the trunk is not necessarily in a perfect production state.

Ok, first thing I'd personally try is the latest libxml2 and libxslt. The guys
over there keep fixing bugs (even really old ones in recent versions), so
things tend to get better over time. For example, I get a reproduceable XPath
crasher in the HTML module Ian is working on with libxml2 2.6.27. It's gone
with 2.6.28. libxslt is a good bet here, too.

Sorry if this doesn't help, but trying other versions is as much as I can
propose at the moment, especially if it's urgent.

Ah, one last thing: I know, you're not testing threads for fun but for
performance, but if that doesn't prove reliable for your application, you can
still switch them off with --without-threading. Reliability is usually more
important than performance for production.
