[issue33042] New 3.7 startup sequence crashes PyInstaller

[Hartmut Goebel]

New submission from Hartmut Goebel <h.goebel at crazy-compilers.com>:

PyInstaller is a tool for freezing Python applications into stand-alone packages, much like py2exe. py2app, and bbfreeze. PyInstaller is providing *one* bootloader for all versions of Python supported (2.7, 3.4-3.6).

In PyInstaller the startup sequence is implemented in
pyi_pylib_start_python() in bootloader/src/pyi_pythonlib.c. The workflow roughly is:

- SetProgramName
- SetPythonHome
- Py_SetPath
- Setting runtime options
  - some flags using the global variables
  - PySys_AddWarnOption -> crash
- Py_Initialize
- PySys_SetPath

The crash occurs due to tstate (thread state) not being initialized when
calling PySys_AddWarnOption.
