In my above case I know that *x won't be deleted because it is global, right?
*x is not deleted since you used PyArray_SimpleNewFromData; that *x is a global is irrelevant here.
Why exactly does the *** glibc detected *** python: malloc(): memory corruption (fast): 0x0817b6a1 *** occur then?
In the code you posted this time, incref() is required so that someone owns a reference to the array object. What I don't know off the top of my head is whether you need an incref in the constructor of A and a decref in the destructor of A.
And is there a way to get the refcount of an object within Python? I'd like to test if the refcount is correct.
sys.getrefcount(obj)
