[New-bugs-announce] [issue8734] msvcrt get_osfhandle crash on bad FD

[Pascal Chambon]

New submission from Pascal Chambon <chambon.pascal at gmail.com>:

In python trunk, _set_invalid_parameter_handler() has been dropped and replaced by custom checking functions, but in msvcrt.get_osfhandle() these checks aren't present, so providing a bad FD leads to a crash.

Here is the little fix + a test (added to test_fileio, because I can't find unit tests for the msvcrt builtin, and similar "bad fd" cases are treated there).
