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:

#

# An unexpected error has been detected by Java Runtime Environment:

#

# SIGSEGV (0xb) at pc=0x00002aaad6a3b072, pid=9698, tid=1187899712

#

# Java VM: Java HotSpot(TM) 64-Bit Server VM (10.0-b23 mixed mode linux-amd64)

# Problematic frame:

# C [jna8479.tmp+0x8072] Java_com_sun_jna_Pointer__1getInt+0x74

#

# An error report file with more information is saved as:

# /JavaCore/hs_err_pid9698.log

#

# If you would like to submit a bug report, please visit:

# http://java.sun.com/webapps/bugreport/crash.jsp

# The crash happened outside the Java Virtual Machine in native code.

# See problematic frame for where to report the bug.

#

Aborted

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

Regards.
