After I step into the crash point, I found that the ncfg parameter is 0[1] and the depth variable[2] is kEGLConfigAttribsRGB24 in CreateConfig().

After including the openGL libraries which are located in prebuilts, I didn't see this crash any more and
I can see boot screen now. I think this could be fixed by bug 1171774.

Hi John, Hi Edgar,
It seems the build is working after you include openGL libraries with bug 1171774. Does that mean we can start Wifi/BT/NFC/RIL proting?  Thanks!

Unfortunately, we still have another blocker, bug 1181481, which also causes b2g unable to boot-up successfully. Before starting porting, we have to do below two things first, 
1. Trying the standalone approach which can fix bug 1181481, bug 1171774 and also this bug.
2. We have to do the first round merge to bring our change from kk branch to the new branch.

I plan to address them in bug 1184418.
