I tried --track-addr=<addr of m_exp_len> But most of the time it is only written at exact the code line it is supposed to be written. So no info there. So perhaps I need a different set of tests? On average I need about 600 runs to catch one SIGSEGV. BTW: tried it on 2 FreeBSD systems, and on both the behaviour is identical. So it has got to be the code. And since 65000 runs on Linux give no errors, it is also typical for the combo FreeBSD/Clang/FreeBSD-packages. --WjW -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
