Minecraft SIGSEGVs and hangs on exit, MC head dev says it's on the JRE

[David Harmon]

Nearly every time I exit the Minecraft program on my Ubuntu system, it crashes with a SIGSEGV. After this, the window frame remains (solid black) and does not respond to close requests. A few minutes later, it closes and posts a system message to the effect of "the program "java" closed unexpectedly. [...] Your system does not have enough memory to automatically analyze the problem."

Here are the exit messages from the console:

I will try to attach the named logfile.

I have tried reporting this to the Minecraft bug tracker, and the head developer (Dinnerbone) has said it's a JRE issue: https://mojang.atlassian.net/browse/MC-146

Status changed to 'Confirmed' because the bug affects multiple users.

Hi David,

You have a ATI ?

[David Harmon (dmh-phoenix)]

Timothée Girard: I have an Alienware system, I've never been able to nail down exactly what graphics card/chip it uses.

[Timothée Girard (girard-timothee)]

@David: I see that in your logfile:
"RBP=0x00007f8ff8eab932: <offset 0x96932> in /usr/lib/fglrx/libGL.so.1 at 0x00007f8ff8e15000"

fglrx is the name of ATI proprietary driver and I think this proprietary is the cause of problem. Because at beginning I use the free drivers and I don't the problem, Minecraft exit normally. And when I install the ATI proprietary driver the problem come out like you.

Infortunately, I don't think there is a solution because the source code of proprietary driver is close and may be ATI stop the support for your graphic card's like me (ATI HD4650 Mobility).

Sorry for my english, I'm french :)

[Timothée Girard (girard-timothee)]

@David: To determine your graphic card's, execute the command line: lspci -vnn | egrep "VGA|3D|Display"
For example and for me, it says :
"02:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI M96 [Mobility Radeon HD 4650] [1002:9480] (prog-if 00 [VGA controller])"
