 The blocking on the futex is also what happens in bug 75007.

 (unlike bug 75007, though, I can duplicate this on non-smp boxes)

+Could you re-run this under Mono
+Also, within gdb please run:
+  (gdb) p mono_print_method_from_ip (ADDRESS)
+for each top-level stack frame ADDRESS that has "??" as the method, e.g.
+  (gdb) p mono_print_method_from_ip (0xffffe410)
+This will show the managed stack trace.  Attach the output to this
+report as well.
+Personally, it looks like it's caused by memory corruption, as you
+have stack frames located at address 0x00000000 within all of your
+threads.  You might try running mono within valgrind, though this may
+require disabling the GC (see the GC_DONT_GC environment variable).
