> Any updates here please? I see those fonts are still FTBFS.

I updated my upstream PR https://github.com/python/cpython/pull/8043 to not
only allow to call Py_Main() after Py_Initialize(), but also to update sys.argv
from the new configuration.

Miro confirmed that my PR fixes fontforge:
https://github.com/python/cpython/pull/8043#issuecomment-406629309

I just merged my PR to master and I'm backporting it to Python 3.7:
https://github.com/python/cpython/pull/8352

Sorry for the delay, Python initialization code is very complex and so very
fragile. I hesitated how to fix the ssue. I chose to write the smallest fix
just to repair fontforge. More enhancements will only be done in the future
Python 3.8.

--- Comment #20 from Victor Stinner  ---
I looked one more time to the issue:

* fontforge code is fine: it calls Py_Initialize() before using the Python C
API to initialize its Python namespace (modules, functions, types, etc.), and
later it calls Py_Main().

* Python 3.7.0 is wrong: it fails with a fatal erro when Py_Main() is called if
Py_Initialize() has been called previously. It is a regression since it worked
fine in Python 3.6.

* My PR https://github.com/python/cpython/pull/8043 works again the simplest
test: "fontforge -script hello.py" where hello.py is just "print('Hello
World!')"

* This PR is not enough according to Miro, since fontforge requires sys.argv to
be set, whereas sys.argv is no longer set when Py_Main() is after
Py_Initialize():

It appears fontforge got built successfully now. As part of other bug 1596037
fix, Kevin attempted new fontforge build and its successful.

--- Comment #13 from Nick Coghlan  ---
The relevant upstream issue has moved: https://bugs.python.org/issue34008

This is due to the fact that Py_Main() doesn't call Py_Initialize() internally
any more (which is why the fix for https://bugs.python.org/issue33932 didn't
fix the fontforge failure after all).

Instead, both Py_Main() and Py_Initialize() call the new lower level
interpreter bootstrapping API directly.

--- Comment #12 from Nick Coghlan  ---
As an interim workaround, I'd suggest trying a CPython patch that changes the
following lines to return Py_INIT_OK() instead of reporting an error:

*
https://github.com/python/cpython/blob/5bb5bbfca847524bab5f2368bdb48eedf5dba74f/Python/pylifecycle.c#L619
*
https://github.com/python/cpython/blob/5bb5bbfca847524bab5f2368bdb48eedf5dba74f/Python/pylifecycle.c#L797

I'm not sure it'll work, but it's worth a try to see if it's enough to emulate
the old "It's like running Py_Main(), but without actually configuring the
interpreter from the environment and command line properly" behaviour.

Victor, would you be able to provide a workaround patch for fontforge? Naively
removing Py_Initialize doesn't solve this.

--- Comment #10 from Victor Stinner  ---
Oh no. My change https://bugs.python.org/issue33932 didn't fix fontforge :-(
fontforge calls Py_Initialize() and then Py_Main(). It seems like my fix
doesn't cover this use case. I didn't expect that an application embeds Python
using Py_Main(). For me, Py_Main() was only used by Python itself.

I reopened the issue upstream: https://bugs.python.org/issue33932#msg320665

For fontforge, the workaround/fix is to not call Py_Initialize() before
Py_Main().
