Comment (by osa1):

 I found a data race in the garbage collector and submitted a patch for
 this. I can't confirm that it fixes the original report (as I couldn't
 reproduce it) but it fixed the assertion failures I reported in comment:1.

 Alp, were you able to reproduce the original error locally? If yes could
 you try again with my patch?
