[PD-dev] external failure OS X

Hi Th have written an external that calls a framework. This basically contains a Struct (called muioObjRef) with a number of sub classes.

Other wrappers to this framework are fine, but PD dies as soon as I load a patch that calls the external. Is there something obvious that I am overlooking?

so having the line

muioObjRef muio;

is fine (where muioObjRef is defined within the framework). But then if I add the following in the constructor for the external

muio = init_muio();

Where init_muio() returns either null or a completed muioObjRef depending on successful initialisation. PD dies without a even a whimper when I call the external.

Any ideas are welcome!
