Bug description
With the minimal code below a `W0612` warning is produced for the second except, but it goes if a different variable name is used instead of `exc`. For some reason, using the same variable name in both except blocks confuses the linter and causes the false positive.
try:
pass
except TypeError as exc:
print(exc)
except ValueError as exc:
print(exc)Configuration

I'm using Visual Studio Code Pylance, so the command is like:
`python.exe -m pylint --reports=n --output-format=json --clear-cache-post-run=y --from-stdin minimal.py`Pylint output

}Expected behavior
No W0612 warning issued for that code.
