Well... You can try to use kgdb7111 from ports, perhaps it would work better. Also, it's often possible to find values of wanted variables by finding a relevant value that's not optimized out and then following through pointers, etc to get to the right values. in other cases it's possible to get the values by examining the disassembly and values of registers. Finally, if you can get anything useful out of the dump it would make sense to follow up to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203419 -- Andriy Gapon _______________________________________________ firstname.lastname@example.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
