The behavior is undefined if such program is executed. implementation-defined behavior- The behavior of the program varies between implementations, and the conforming implementation must document the effects of each behavior. For example, the type ofstd::size_tor the number of bits in a byte, or...

You can override the behavior for new on the C++ side though (we have some tests to demonstrate this). See work #1693 . Then you can have the C++ class call any new method you want, see pybind11/tests/test_class.cpp Line 89 in 442261d .def_static("__new__", 👍 1 ...
cout << i << i++; // undefined behavior (until C++17)a[i] = i++; // undefined behavior (until C++17)'''所以现在的问题是- 为什么会出现undefined behaviors of evaluation order- 为什么要对其进行修改- 还有一个其他问题就是上述的unspecified behavior是什么?在cppref没有找到定义。

The question is now, what the expected behavior in this case is, especially in light of the different behavior on stable (of course intel-tex-rs-2 could remove that code, since it's not implemented anyhow). Member bjorn3 commented Jan 9, 2025 I think it is expected that you may get...
