Yes, there are a few.

In some cases this is to make it easier to call them from
infrastructure or macros which doesn't necessarily have a gc, eg the
logging functions, and the way that libxl__ao_create obviously is
_creating_ the gc (as well as the ao) for its caller.

In other cases it's just to avoid needlessly pratting about with
GC_INIT.  (Note that in the past, that pratting about was considerably
more verbose.)

It isn't in general a bug to have nested calls to GC_INIT.

Ian.
