--- Comment #6 from Konstantin Belousov <[email protected]> --- (In reply to Andrew Stitcher from comment #5) Depending on whether libpthread linked into the process or not (as well it might be not linked but loaded later), libc changes its algorithms. For instance, stdio FILEs are locked if libpthread is present, and not locked otherwise. Similarly, rtld uses real (but custom) rw locks to protect it internal state if libpthread is there, otherwise it just masks signals using cheap sigfastblock(2) backdoor. This is why I asked whether it acceptable to change the C runtime behavior by sneaky linking with libpthread if ASAN is used. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
