Issue: QT5.5.1 APP Coredump
Occurrence rate: Always 
Precondition: 
1. Install the QT5-5.5.1 environment base on screen-j6-2018-04-27.
2. Install the QT5-5.5.1 app "screentest"
Steps: 
1. Execute the app "screentest".
Results: 
1. APP Coredump
Expected behavior: 
1. APP Run and show the HMI UI.

Comments:
After we update the new screen patch "screen-jacinto6-2018-04-27-spectre-660-B376.tgz", the recompiled APP will be coredump.
From the coredump file, we locate the coredump location. "0x7de88674 in ScheduleTA () from libImgGLESV2.so "
we have some questions that need your support:
1. what reason maybe causes this app coredump?
2. how can we get more information about openGL debug information, When issue happened?
