Not sure if it's closely related, but we had a somewhat similar CFNetwork crasher that turned out to be a WebKit issue in bug 55412.

This is on my shiny Lion iMac. Can't use DRT anymore. I've verified through manual printf() that it enters DumpRenderTree main(), but it stops after we initialized the NSURLCache, at some point, when its thread fires and tries to open the sqlite3 database, it just crashes. No idea why.

No idea why. Could you set aside the relevant Cache.db file (from ~/Library/Caches) and see if it goes away? And if so, could you please attach that Cache.db file?

(In reply to comment #6) > And if so, could you please attach that Cache.db file? I've tried that, it did not help. I stopped testing as I discovered that "valgrind sqlite3 foo.dbg" yields the same problem. It turns out my valgrind trunk checkout was dated, with latest ToT valgrind works just great on Lion!
