Ah, so check-qjson.c is another culprit.  Yes, this is one of the places
I'm cleaning up in my upcoming patches for 2.8.

I did run make check. It fails here:

That sounds like an independent failure; can you run 'gdb
tests/check-qjson' and get a backtrace for that (perhaps in a new
thread, since fixing it is different than this thread on
improving/eliminating qobject_from_json[fv])?



check-qga isn't run.


'make check -k' will let it run, rather than giving up early on the
first test failure of any earlier test.
