That's an odd backtrace.
As far as I can tell you have compiled everything fine yet it tells me
that run_query is blowing up in a subcall to caml_ml_close_channel
(which is the underlying c call for close_in and close_out).
I might be reading this bt wrong. Otherwise there's something fishy
with your stack. Whatever it is, I am very confused by this all. Would
you mind posting your code to see if other people can reproduce the
problem?
Cheers,
Till
