Thanks! So all LPython tests pass for you, but some CPython tests fail?

It's weird that we didn't hit these errors earlier. We'll try to reproduce this and fix it.

[BenWibking]

What do you mean by LPython tests vs. CPython tests? If you mean the tests run by this script (https://github.com/lcompilers/lpython/blob/main/run_tests.py), then yes, those all pass:

[Smit-create]

What do you mean by LPython tests vs. CPython tests?

The integration tests have different backends like LLVM, C, and CPython. LPython is used to compile and run the tests with LLVM and C backend.

[Thirumalai-Shaktivel]

Try Python 3.10 and see if it fixes the issue.
Edit: We will try to debug and fix the issue with Python 3.11

[certik]

We'll definitely fix this. As @Thirumalai-Shaktivel said, see if Python 3.10 works for you, that way we will know for sure that the issue is with Python 3.11.

[BenWibking]

Yes, with Python 3.10, all tests pass:

100% tests passed, 0 tests failed out of 304

[certik]

@BenWibking awesome, thanks!

It's interesting, our experience so far is that the most fragile thing of all of LPython is the lpython.py "emulation layer", it's just this one simple file: https://github.com/lcompilers/lpython/blob/8df052e174adbd789fc7b03f5526e706195b3543/src/runtime/lpython/lpython.py, less than 800 lines. In this case it seems the issue is interaction of numpy and dataclasses with packed members. I created #2274 for general simplification of this file.

[certik]

@Shaikh-Ubaid, great job!
