[New-bugs-announce] [issue43707] onerror in tempfile has an invalid raise expression

[Maximilian Roos]

New submission from Maximilian Roos <m at maxroos.com>:

The raise expression [here](https://github.com/python/cpython/blob/ad442a674ca443feec43a88a2d3671784712e550/Lib/tempfile.py#L826) isn't valid, since it isn't in an except block.

It'll still raise, given it's invalid, though not with the exception it should be raising with...

I think this diff will fix it, I can put this in as a PR if that's reasonable. Though I'm not sure how to test it — we need to generate an error that's not covered by the existing cases.
