Updating to master, noticed a new issue relating to kwargs. Last working commit is bb70874. On commit 1e99d29, I get a core dump, and 783b1a8 onwards, I get a TypeError.

I'm running IDF v4.4. I'm running this on ESP S3.

ERROR 2e3f204 (HEAD -> master, origin/master, origin/HEAD) py/runtime: Use size_t/ssize_t instead of uint/int.

Here's the test case. This schtick on this one is direct instantiation of kwargs is working fine. Which is why it probably passed test cases (and why this was a little tricky to find). But when you pass kwargs through a function, I see the issue.

def kwargs_test1(kwargs):
    KwargsTest(**kwargs)
class KwargsTest():
    def __init__(self, hello            = None,
                       world            = False,
                       ):
        pass

kwargs = {'hello':True}

#direct instantiation works across commits
KwargsTest(**kwargs)
# <KwargsTest object at 3d832510>

#calling via function causes error on new commits
kwargs_test1(kwargs=kwargs)
# on commit bb7087411 and earlier, no error.
# on commit 1e99d29f3 core panic
# on commit 783b1a868 and owwards, I get this:
# Traceback (most recent call last):
