Hi.
I tried enabling the setProtected before, and it didn't help - the app
always crashed. I do recall that it was due to some possible issues in the
native code, so it worth trying again.
If it does not work - what other means I have to track the issue? Is there
any way at all to get core dumps and check them?
Also, by meaning the who owns the pointer, you mean that somewhere I'm
trying to access invalid int pointer?
Regards.

Do you have any more stack? If not, if you run with -Djna.protected=true
(or Native.setProtected(true)), the SEGV should throw a java.lang.Error
instead of crashing.
You'll need to determine who owns the pointer value being used and how it
got to be invalid (if it's really failing in Pointer.getInt).

Hi.
I'm trying to hunt an issue of JNA sporadically crashing after working
some time normally, with a high number of concurrent threads (40+). The
problem seems to be within JNA, as the log shows:

Aborted
Any idea how I can hunt for this one, or how this crash could be prevented
at all?
Regards.
