Strange crash with pyglet, wxwindows and multiprocessing #490

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
Simply importing wx will cause the following program to crash. Commenting out 
the import wx will allow it to run normally. Note that wx is not used at all. 
Setting shadow window to false before opening a pyglet window does not fix the 
problem.

#CODE-------------------------------------------------

import multiprocessing as mp
import wx

def run():
  import pyglet
  w = pyglet.window.Window(resizable=True)
  while not w.has_exit:
    w.dispatch_events()
  w.close()

p = mp.Process(target=run)
p.start()
p.join()
