This only happens if eglMakeCurrent is called twice, which is the case in my
program and in wayland also (e.g. there's a call to eglMakeCurrent followed by
a call to cairo_egl_device_create, which also calls eglMakeCurrent).
Since we use the surfaceless extension the first call to
st_manager.c:st_api_make_current uses an incomplete buffer as a dummy (I
think?), so then:
(gdb) print stfb ==
$11 = 1
In the next call the following check at st_manager.c:730 :
if (stdraw && stread) {
passes but:
(gdb) print stfb->iface
$28 = (struct st_framebuffer_iface *) 0x0
So there's a null dereference. I'm not familiar with mesa so I can't help with
a (correct) patch.
