Log of job that crashes

Built from branch

We get another sgen crash, Thread 10, in sgen_optimize_pin_queue(...) in sgen-pinning.c:159

  while (*start == *cur && cur < end)

Another null ptr dereference? Will try to build a minimal testcase, though these failures are really hard to hit reliably.

Could you try with master? We have fixed a couple of issues there.

Can you still reproduce with latest version of mono? If you can, please reopen and provide a repro case. Thank you
