There is no need to set EGL_PLATFORM in this case and generally.
"dri" is also an invalid value.

Without

  $ export EGL_DRIVERS_PATH="/home/muthu/work/game/gallium/mesa-master-llvm-gcc-egl/lib/egl/"

it is likely that the wrong driver is loaded.  You can set
EGL_LOG_LEVEL=debug to see which module is dlopen()ed; if you suspect
the crash is in llvmpipe, you may set GALLIUM_DRIVER=softpipe to see
if it still crashes.  Either way, a gdb backtrace is helpful.
