Bug report

Bug description:

PyArg_ParseTuple seems to handle incorrectly if an integer/integers and a boolean/bool are passed as arguments to parse, e.g. for the format string "ip" or "iip", etc. It then produces the incorrect value for the first integer argument. In my code I get zero value for that first integer argument, and correct values for the the rest of the arguments. The issue seem to disappear if the qualifier for the boolean argument "p" is replaced with the integer one "i". The issue is also not there for the "Op" format string, e.g. when a Python object and a boolean are passed as arguments.

To illustrate the issue I created an example module that reproduces the bug. (The code is a bit too long to place it here directly, since it has to be a C extension)

CPython versions tested on:

3.12

Operating systems tested on:
