After some debugging, it crashed in
dri2_client_wait_sync() of
...src/egl/drivers/dri2/egl_dri2.c
The ctx returned by _eglGetCurrentContext()
is NULL.

static EGLint
dri2_client_wait_sync(_EGLDriver *drv, _EGLDisplay *dpy, _EGLSync *sync,
                      EGLint flags, EGLTime timeout)
{
   _EGLContext *ctx = _eglGetCurrentContext();

==> ctx is NULL

   if (dri2_dpy->fence->client_wait_sync(dri2_ctx->dri_context,  <== OOPS!
                                         dri2_sync->fence, wait_flags,
                                         timeout))


Why does _eglGetCurrentContext() return NULL?
Any recommended fix?
