[New-bugs-announce] [issue2833] __exit__ silences the active exception

[Dmitry Dvoinikov]

New submission from Dmitry Dvoinikov <dmitry at targeted.org>:

If a context manager is used within exception handling block, the active
exception is silenced after the context block completes and __exit__ exits.

try:
    raise Exception("foo")
except:
    with SomeContextManager():
        pass
    raise # in Py2.5 throws 'foo', in Py3.0 fails with RuntimeError
