Based on my preliminary efforts to isolate the problem, it seems pretty clear that A) the code path required to reach the error is not exposed by the malloc API to applications (after all, how could an application call "free" recursively?), and B) it likely has something to do with an overlooked race condition in the thread safety retrofit of libc late last year. But, as was mentioned previously, XFree86 3.3.6 doesn't have the required chip support for the Dell 5000e, so that's not an option, regardless. I welcome further suggestions, though. -Michael Robinson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
