Bug report

Bug description:

while x:
    0 if 1 else 0 # 1 can not be 0 to reproduce this bug

output (Python 3.12.0rc3+):

python: Python/flowgraph.c:114: basicblock_addop: Assertion `0 <= oparg && oparg < (1 << 30)' failed.

I tested this with the current 3.12 branch (6f1d455)
@iritkatriel I think this is again something like #109719 or #109627

CPython versions tested on:

3.12

Operating systems tested on:

Linux
