[issue33932] Calling Py_Initialize() twice now triggers a fatal error (Python 3.7)

[STINNER Victor]

STINNER Victor <vstinner at redhat.com> added the comment:

I reopen the issue because fontforge still fails on Python 3.7.0 final. fontforge calls Py_Initialize() and then calls Py_Main() which fails with an assertion: https://bugzilla.redhat.com/show_bug.cgi?id=1595421

The same code works well on Python 3.6, so should we define this issue as a regression?

Call stack:

* Py_Main()
* pymain_main()
* _Py_InitializeCore() which fails

The problem is that the first call of Py_Initialize() sets a first configuration, but then Py_Main() sets a different configuration.

Is it correct to call Py_Initialize() before Py_Main()?
