    Hello,
    I have a multithreaded application ported on FreeBSD 5.3 which crashes
    in a minute or less if hyperthreading in enabled. Without HT there is no
    problem.
    How and where should I start to investigate the problem?

    The backtrace:
    (gdb) bt
    #0 0x2819631b in pthread_testcancel () from /usr/lib/libpthread.so.1
    #1 0x2818e902 in pthread_mutexattr_init () from
    /usr/lib/libpthread.so.1 #2 0x00000000 in ?? ()

    Thank you
