Uh, Daniel and I are in total agreement on this one; I don't know what I'm supposed to have pointed out, but I was basically going off a conversation between Daniel and an nVidia user, and my understanding of the threads library code in the three libraries. BTW: a corrupted %gs can crash a user space program that's threaded and expects a different value, without actually crashing the kernel: it all depends on who trashes who's %gs first, since if you crash in user space from a %gs set by the kernel to an unexpected value, then you aren't going to get the opportunity to set it to a value that will crash the kernel becase, well, having crashed, you aren't runnung any more to execute the code to do it. 8-). -- Terry _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
