vtest doesn't implement the according API and would segfault:
Program received signal SIGSEGV, Segmentation fault.
#0 0x0000000000000000 in ?? ()
#1 in virgl_fence_server_sync at
src/gallium/drivers/virgl/virgl_context.c:1049
#2 in st_server_wait_sync at
src/mesa/state_tracker/st_cb_syncobj.c:155
so just don't do the call when the function pointers are not set.
Fixes dEQP:
dEQP-GLES3.functional.fence_sync.wait_sync_smalldraw
dEQP-GLES3.functional.fence_sync.wait_sync_largedraw

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
<https://dri.freedesktop.org/wiki/WhosWho/>`_.
The next best option is to ask your question in an email to the
