Crash when importing QtCore with PySide 6.8

With PySide 6.8.0 installed, qtpy will crash without raising an Exception when importing QtCore from qtpy. The crash happens in "./qtpy/QtCore.py", line 128: from PySide6.QtCore import *.

Hey @maflAT, thanks for reporting. This seems similar to issue #480, in the sense that PySide 6.8 seems to have broken star imports again (i.e. imports of the form from PySide6.QtCore import *).

Since Qtpy is simply a wrapper around PyQt and PySide, there's nothing we can do about it. Instead, please report this problem in the Qt bug tracker and kindly ask them to run our test suite before releasing a new minor version to avoid this problem in the future.

Note that the crash is a CPython crash, i.e. an access violation (exit code 0xC0000005) on windows, i.e.;

import qtpy.QtCore

crashes with 0xC0000005 and;

import PySide6.QtCore

exits normally with exit code 0.

See attached test.bat file.

This bat file outputs;

My guess is that the 6.8.0.1 from pypi resolved things they released it today.

On conda-forge we also released a backport though we called it 6.8.0 build 1 https://github.com/conda-forge/pyside2-feedstock/pull/249

Upstream seems to have added a test for star imports too.

In the fact the bug report I originally opened refers to 6.8.0.1 as having the fix: https://bugreports.qt.io/browse/PYSIDE-2888

Closing since I think there is not much from the QtPy side to do for this and also PR #523 adds Qt 6.8 to the CI matrix and seems like things are passing
