SIGSEGV when closing JOGL applications
— by Justin Justin
Hi all,

I've been developing with JOGL for a little over a year now, but I've started having an annoying bug when I upgraded to Ubuntu 10.04 recently. JOGL programs work fine, but whenever I close them down I get a SIGSEGV error and a .log file is generated with some extra info. Here's an example (top/bottom parts of message for brevity):

# A fatal error has been detected by the Java Runtime Environment:
#  SIGSEGV (0xb) at pc=0x00007fecb888bc98, pid=1966, tid=140654704224016
# JRE version: 6.0_20-b02
# Java VM: Java HotSpot(TM) 64-Bit Server VM (16.3-b01 mixed mode linux-amd64 )
# Problematic frame:

This happens with other user's applications as well, so I don't think I'm doing anything strange in my programs that would be causing this. I haven't seen this error in other versions of Ubuntu or Windows. I'm using Sun's Java. Any idea what might be going on here?
