Engineering has requested the following information in order to further investigate this issue: 

- Please attach relevant crash logs to this bug report.

--- Crash Logs Instructions ---
https://developer.apple.com/bug-reporting/ios/crash/

Crash Logs are usually saved to the device when an application unexpectedly quits.  To retrieve the crash log, connect your device to your computer.  iTunes should open automatically and copy the crash log to your computer. If iTunes does not copy the crash log, select your device in iTunes and click "Sync."

The crash log can then be found in one of the following locations, depending on which platform you use and what operating system you're using on your host computer:

• Mac OS X:

~/Library/Logs/CrashReporter/MobileDevice/<device name>/

Note: "~/" actually means /Users/[Your User Name]/Library/Logs/... not the root path /Library/Logs/.

• Windows 8:

C:\Users\[Your User Name]\AppData\Roaming\Apple Computer\Logs\CrashReporter\MobileDevice\<device-name>\

Note: The AppData folder is hidden by default. Click on the View menu item in a Windows navigation window and check the "Hidden items" checkbox and the AppData folder will appear in the list of folders under C:\Users\[Your User Name].

• Windows Vista:

C:\Users\<Your User Name>\AppData\Roaming\Apple Computer\Logs\CrashReporter\MobileDevice\

Note: The "AppData" folder is hidden by default.  Choose Organize > Folder and Search Options the file browser window, then click the View tab and change the "Hidden files and folders" option to "Show hidden files and folders."

• Windows XP:

C:\Documents and Settings\<Your User Name>\Application Data\Apple Computer\Logs\CrashReporter\MobileDevice\ 

Note: The "Application Data" folder is hidden by default.  Choose Tools > Folder Options in the file browser window, then click the View tab and change the "Hidden files and folders" option to "Show hidden files and folders."

Bug ID #: 23538812
Bug Title: Apps crashing when compositing images on MacBookAir4,1 IntelHDGraphics3000
--------------------------------------------------------------------------------------------------------------------
<GMT13-Nov-2015 20:27:02GMT>
Summary:
This crasher seriously affects my application Acorn on 10.11.

I've got a really simple sample project which reproduces the behavior 100% of the time.  Basically, composite a bunch of images together and try and draw them, and the sample code will crash in the bowls of AppleIntelHD3000GraphicsGLDriver.

Customers are frustrated, and I see other applications are affected by it as well.  I know it's older hardware- but it'd be great if this was given some priority.

Steps to Reproduce:
1. Get a MacBookAir4,1 (or possibly any mac with an IntelHDGraphics3000 card).
2. Install Xcode.
3. Run the sample code.

Expected Results:
The sample application would run without crashing.

Actual Results:
The application crashes

Version:
10.11.1

Notes:
This is a regression, and I'm not aware of any workarounds.

Configuration:
MacBookAir4,1

MacBookAir4,1-10.11.spx - configuration file has been successfully uploaded.

Attachments:
'GLDriverCrasher.zip' and 'MacBookAir4,1-10.11.spx' were successfully uploaded.
