Comment (by ezyang):

 Here is the most common trace I get:

 {{{
 [Current thread is 1 (Thread 0x2b203c5129c0 (LWP 3558))]
 (gdb) bt
 #0  0x0000000000000000 in ?? ()
 #1  0x0000000000000000 in ?? ()
 }}}

 However, I got lucky on one run and here is a more useful trace (I've
 posted it here http://hs01.scs.stanford.edu/ ):

 Here's another one I got:
