[New-bugs-announce] [issue45262] crash if asyncio is used before and after re-initialization if using python embedded in an application

[Benjamin Schiller]

New submission from Benjamin Schiller <benjamin.schiller at vector.com>:

We have embedded Python in our application and we deinitialize/initialize the interpreter at some point of time. If a simple script with a thread that sleeps with asyncio.sleep is loaded before and after the re-initialization, then we get the following assertion in the second run of the python module:

"Assertion failed: Py_IS_TYPE(rl, &PyRunningLoopHolder_Type), file D:\a\1\s\Modules_asynciomodule.c, line 261"
