You can build it yourself,
% ant -Ddebug.native=true clean jar

Other than that, it looks like memcpy is getting passed a bad pointer.

i have multi thread daemon using JNA which frequently crashes with the folowing error (full dump attached):

The daemon uses FFMPEG library (libavcodec) through Java-FFMPEG bindings, which in turn use JNA.
I need any way to either solve the issue, or to isolate the crashing thread and not allow the crash to propogate to the rest of the daemon.
Please assist, I'm trying to solve this for the entire last week.
If the source code required, any tips of locating the offending FFMPEG C++ function would be appreciated (currently, as you see, it only shows the point of crash but not the c++ functions stack).
Thanks to anyone who will reply.
