The worker process crashed (signal 11). This is certainly a problem in the
upload module, but to be sure can you recreate your test without the
upload module compiled in.
If that doesn't crash, then please enable nginx debug (--with-debug) and
redo your upload test, then send me privately
(brice+nginx at daysofwonder.com) the debug log file.

Also, what version of nginx are you using, and under what operating system?
I'll try to reproduce the problem, but I want to be sure we are running
the same environment.

Thanks,
