[PD] Strange behavior using custom external

[GCC]

Below is my setup method.  This object generates rhythmic phrases so it
accesses the time scheduler in Pd as per the code [metro] or [delay], and
outputs a bang.  Perhaps this could be where it goes wrong?

  Thanks for your time and help.

void rhynamo_setup(void) {

        

        

        rhynamo_class = class_new(gensym("rhynamo"),

                                 (t_newmethod)rhynamo_new,

                                 (t_method)delay_free, sizeof(t_rhynamo),

                                 CLASS_DEFAULT,

                                 A_GIMME, 0);

        

        post("[rhynamo] a rhythmic generator v .02 : by Robert Esler 2014");

        

        class_addbang  (rhynamo_class, rhynamo_bang);

        class_addfloat(rhynamo_class, (t_method)rhynamo_generate);

        class_addsymbol(rhynamo_class, (t_method)rhynamo_set);

        class_addmethod(rhynamo_class,

                        (t_method)rhynamo_set, gensym("set"), A_DEFSYMBOL,
A_DEFFLOAT, 0);

        class_addmethod(rhynamo_class,

                        (t_method)rhynamo_generate, gensym("generate"),
A_FLOAT, 0);

                

        class_sethelpsymbol(rhynamo_class, gensym("help-rhynamo"));

        

        

    }

The difference probably indicates that something is going on in your
_setup() function.  Once you've loaded a class in a patch, it stays in
memory.  If you close the patch, and open another patch without the class,
you may still see the effects---but if you close pd, and reopen without
using the class, you should not see the effects at all.

The backtrace shows a seg fault from calls in "binbuf_eval", which is the
code related to parsing and loading a patch.  You might just have passed a
struct as an argument, where it's expected to be an element of that struct.

Although.... pointer type mismatches will definitely throw a compiler
warning you should have seen already.  Would you post the _setup() function?
