Looks like it's trying to use the X11 EGL backend, which can't work in the X
server. Was 'drm' included in the --with-egl-platforms= parameter to Mesa's
configure?

yes, mesa is configured with "--with-egl-platforms=x11,drm"

How are you starting the X server? Does the shell which starts the X server
contatin the environment variable EGL_PLATFORM=x11, or does it help if you set
EGL_PLATFORM=drm?

Either way, please set the environment variable EGL_LOG_LEVEL=debug for
starting the X server and attach its stderr output.

So you set EGL_PLATFORM=drm? Would be interesting to see the debugging output
without that as well.

That's not the same crash anymore, but 'just' an EGL initialization failure.
Does it get further if you set EGL_DRIVER=egl_dri2 as well?

Yet another crash... Can you get a backtrace for this one with gdb? You'll need
to do that from a remote shell, e.g. via ssh.

I think it is a regression issue. The issue is resolved with upgrading mesa to
latest 9.3.0-devel(git-59157d1) and with glamor-0.5.0

Looks like you were hitting this crash again in bug 69961. Was it upgrading
Mesa or downgrading glamor which resolved it before?

Sorry for the delay. I was under the impression that bug is closed.
I think downgarding glamor resolved the issue that time but again segmentation
fault is observed 
on startx when building glamor with git master with xv enabled by default.

Xserver version is 1.12.99.905 and this is the backtrace:
