[issue17206] Py_XDECREF() expands its argument multiple times

[Jeremy Kloth]

Jeremy Kloth added the comment:

Here are some results after a detailed investigation:

- in debug, each variable declaration in a block is allocated on the stack
- in debug, r_object() uses 1416 bytes of stack 
- in release, r_object() uses 512 bytes of stack
- default stack size is 1MB
- stack for python_d.exe has been already up'ed to 2100000

So it seems that the best option would be to increase the stack size used when linking (/STACK:).  I would suggest increasing it to 3MB using /STACK:3145728.
