Snapdragon profiler crashes when using KHR_debug glPushDebugGroup

I'm using the Windows 2018.3 build of the Snapdragon profiler with a Google Pixel phone running Android 9.  I have a small tool which loads a serialized frame from a larger application and plays it on a loop so I can use profiling tools on a shorter development cycle.  

However, I've discovered that when I use the KHR_debug extension functionality, attempting to take a snapshot causes a crash.  glPushDebugGroup and glPopDebugGroup are available in OpenGL ES 3.2, and glPushDebugGroupKHR and glPopDebugGroupKHR are available in any device with the KHR_debug extension.  

My Pixel supports both, but no matter which I use, attempting to take a snapshot when these functions are in use crashes Snapdragon Profiler with no error message.

Thank you for posting the bug report.  Yes, there was a crash when using the glPushDebugGroup and glPopDebugGroup calls with SDP version 2018.3.  It has since been fixed, and will be included in the next release of Snapdragon Profiler.  In the meantime, you may be able to workaround the issue by passing in the actual string length into those calls.

 

Thanks,

Ben
