OpenGL calls causes Simulator to crash on Sandy Bridge mcbook

[artbox]

Hi

on the new Sandy Bridge Mcbook pro (2011), the IOS simulator (4.3 Target) will systematically crash when some OpenGL functions are called. Testing for 4.2 works fine though.
Even the default Xcode OpenGL ES project template doesn't work.
I've tried reinstalling XCode 3.2.6,
Xcode 4, and even reinstalled OSX from scratch but without any success.

Anyone has similar pb? could it be a hardware related issue on the new MBP (Sandy Bridge), coz the same code would work perfectly on a 2010 MBP, 2009 iMac, and 2008 mcbook?

So far I've managed to pin down the 'glDrawArrays()' function to be the cause of the crashes. and here is beginning of the error msg i get in the debug:


LVM ERROR: Cannot yet select: 0x5831d10: v4i32 = bit_convert 0x5838350 ORD=129] [ID=69]
0x5838350: v8i16 = X86ISD::PUNPCKLWD 0x58157b8, 0x5832370 [ID=68]
0x58157b8: v8i16 = bit_convert 0x58382c8 [ORD=127] [ID=67]
0x58382c8: v16i8 = X86ISD::PUNPCKLBW 0x58158c8, 0x5838718 [ID=66]
....
..
.

thanks

I also have the new Sandy Bridge MBP and I'm having exactly the same issue.
Like you, I found the crash to occur when the glDrawArrays function is called. I'm getting the same error message.

The issue started happening when I began using the iOS SDK 4.3 to compile the GLPaint sample from Apple. The default Xcode OpenGL ES template doesn't work for me either.

The 4.2 SDK works with no problems.

Please help...

The problem started also having just upgraded to Xcode 4.

I have the exact same problem. Has anyone seen a solution yet?

The only case in which there is a problem for me is in the iPhone 4.3 Simulator.
Testing on my iPhone device with iOS 4.3 installed works.
Testing in the iPhone 4.2 Simulator also works.

I'm using Xcode 4.
