Hi,
I was trying to implement asynchronous driver which is invoked in a
separate thread. It crashes with "segmentation fail" message when second
call is issued, in driver_async().
I'm attaching dummy short test which shows the problem. I intentionally
removed from the code most of driver_free() calls to reduce potential
problem source.
following command makes it failed:
erl +A4 -noshell -s drv t -s init stop
but no-thread-pool one works fine:
erl -noshell -s drv t -s init stop
Tested in R11-0, R11-2, smp and non-smp Linux.
Any idea / help is appreciated.
Thanks.

Thanks for the bug report.
We have found the bug and we will include a correction in R11B-3
(probably to be released within 1 or 2 weeks).
