https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D215798 Dimitry Andric <dim@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dim@FreeBSD.org --- Comment #1 from Dimitry Andric <dim@FreeBSD.org> --- The problem is that the thread sanitizer currently does not work on FreeBSD. This has to do with the way thread sanitizer attempts to initialize very ea= rly during program startup, and it conflicts with jemalloc's early initializati= on.=20 This leads to an endless recursion, and a stack overflow. For thread sanitizer to work properly, it looks like we will need some sort= of hook in libc, which can be used to initialize thread sanitizer before jemal= loc is initialized. I have limited time, so I have not yet worked on this.=20 Patches are welcome. :-) --=20 You are receiving this mail because: You are the assignee for the bug.=
