[issue23188] Exception chaining should trigger for non-normalised exceptions

[Nick Coghlan]

Nick Coghlan added the comment:

After looking into this further, PyErr_SetObject (and other APIs like PyErr_SetString which call that internally) aim to handle the chaining automatically, but they don't handle exceptions which haven't been normalized yet.

PyErr_SetObject should probably normalise the exception at the start of the call f ithe exception type is set on the thread state, but not the exception value.
