[BUG] Adding constructor causes segmentation fault / GlobalError::PushToStack()

Issue description

I am working on esmini-pybind1.
Adding constructor causes segmentation fault / GlobalError::PushToStack()

Reproducible example code

Before defining a constructor

import pyplayerbase
from pyplayerbase import *

x = ScenarioPlayer
print( x )
print( type(x))
print( dir(x))
print( x() )

Results in:

python3 tests/scenarioplayer.py 
<class 'pyplayerbase.ScenarioPlayer'>
<class 'pybind11_builtins.pybind11_type'>
['AddObjectSensor', 'Frame', 'GetFixedTimestep', 'GetOSIFreq', 'GetParameterValue', 'IsQuitRequested', 'ScenarioFrame', 'SetFixedTimestep', 'SetOSIFileStatus', 'SetParameterValue', 'ShowObjectSensors', 'UpdateCSV_Log', '__class__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'callback', 'exe_path_', 'maxStepSize', 'minStepSize', 'opt', 'sensor']
Traceback (most recent call last):
  File "tests/scenarioplayer.py", line 12, in <module>
    print( x() )
TypeError: pyplayerbase.ScenarioPlayer: No constructor defined!

After defining an empty constructor

RosettaCommons/binder generates the following this extra bindings:

cl.def( pybind11::init( [](){ return new ScenarioPlayer(); } ) );

The same script crashes when it tries to import the pyplayerbase module:

$ python3 tests/scenarioplayer.py 
Segmentation fault (core dumped)

---Type <return> to continue, or q <return> to quit---

Start by reproducing the import crash with tests/scenarioplayer.py and the generated pybind11 constructor binding for ScenarioPlayer. Use the shown gdb backtrace, including GlobalError::PushToStack(), to investigate the failure during pyplayerbase import. Done means the module imports without a segmentation fault and ScenarioPlayer can be constructed.
