Caused by: java.lang.IllegalArgumentException: Native call setup failure: 1

Beginning to answer my own question, now that I've found the native source again, the 1 is the result of ffi_prep_cif, and looks to be FFI_BAD_TYPEDEF. What I don't now understand is how sometimes ffi_prep_cif can succeed, and other times fail. Predictably, it always seems to succeed when run under the XCode debugger. Synchronisation? Garbage collection?
