I suspect that it's not a problem with the python object sticking
around, but with the underlying memory. Are you quite sure you're not
mallocing something you're not freeing?
Sorry, I've deleted your original post, but are you passing in a data
pointer to PyArray_NewFromDescr() or PyArray_New() ? if so, then you to
free that memory in your own code.
Anyway, perhaps you could post your array creation code again, and
someone will see something (or just use cython!)
