Preliminaries:
I'm using gutsy
This is definetly a wx problem, but the callstack showes the most recent call
as libg. I can trigger it easily with the following python script
(I run it with "cat | python")
import ctypes
gt=ctypes.CDLL('/usr/lib/libgthread-2.0.so.0')
gt.g_thread_init(ctypes.c_voidp(0))
import wx
class BugApp(wx.App):
def OnInit(self):
self.frame = frame = wx.Frame(None)
# double free or corruption
b = wx.Button(frame, -1, "dfree | corruption", (20,20))
# stranger stuff
b = wx.Button(frame, -1, "free or corruption", (20,20))
self.Bind(wx.EVT_BUTTON, self.OnButton, b)
frame.Show()
return True
def OnButton(self, evt):
wx.TextEntryDialog(self.frame, "some text", "some text")
app = BugApp()
app.MainLoop()
btw, if you change the length of the title in the wx.Button you get different
errors - so basically there is some bad pointer arithmetic going on in that
wx.Button call (which is of course a wrapper for the real wxWidgets call).
(it crashes when you press the button)
HTH,
