https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192098 Mark Johnston <markj@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |Works As Intended Status|New |Closed CC| |markj@FreeBSD.org --- Comment #1 from Mark Johnston <markj@FreeBSD.org> --- memguard targets specific malloc types and zones, whereas UMA does general use-after-free and double free checking for all zones (with some constraints). Compiling memguard into a kernel does not enable it, you have to point it at a particular zone (which the repro steps don't do). -- You are receiving this mail because: You are the assignee for the bug.help
