  under Mac OS X:

  ./Controls/Source/ControlAllocation.cp:755: failed assertion `theErr == noErr'
  Abort

  This is due to the constant kwxMacListWithVerticalScrollbar at line 40 of
  src/mac/listbox.cpp because the custom control definition has not been loaded
  and is not present in memory, see:
