The CellML API provides an API for asynchronous loading, but the actual
loading in that case needs to be done with the program, so I don't think
that is involved here.

I suspect something is getting corrupted, or there is uninitialised
memory somewhere.

I found a bug in the reference counting for math results in the CellML
API, and a bug in the string processing in the Antimony translation -
with both fixes together I don't get any errors (although
antimony2cellml does seem to be leaking memory) - the solution is to
make sure that all calls which expect the caller to release memory
afterwards actually do so; unfortunately, a single missing release_ref()
can cause the entire model representation to leak.

Patch to get antimony2cellml working for me attached.

Best wishes,
Andrew
