https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=233414 --- Comment #4 from Mark Johnston <[email protected]> --- Created attachment 199759 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=199759&action=edit workaround (In reply to Leandro Lupori from comment #3) This is not a powerpc-specific problem, it's a limitation of memguard: some of its internal operation involve allocating from UMA, which might call into memguard again. The attached patch should allow you to guard most UMA buckets. It's a total hack and isn't intended to be committed, but might help you make progress with the use-after-free. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ppc To unsubscribe, send any mail to "[email protected]"
