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.

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?
