--- Comment #4 from Xerxes Rånby <xerxes at zafena.se> ---
I asked the JogAmp team, who also maintains a Java OpenGL binding, about a
second opinion on this bug. My analysis in comment 3 is wrong since this bug
have triggered a SIGILL (execution of invalid instruction) instead of a SIGSEGV
(segmentation fault)

(16:22:48) sgothel:  SIGILL (0x4) at pc=0x00007fec99846040, pid=4471,
tid=140653971465984 -> pointer invalid I guess
(16:23:05) sgothel: looks like they do not validate what they have looked up
via dlsym
(16:27:14) sgothel: SIGILL  The SIGILL signal is sent to a process when it
attempts to execute a malformed, unknown, or privileged instruction.
(16:27:40) sgothel: glGenBuffersARB+0x0 -> invalid

I hope this may help the Jagex developers to fix their OpenGL binding.
