[NEEDS INFO] Model mapping patch triggers OS X Window manager event handling errors

[Doménique]

On OS X the modelmapping patch by Myconid triggers non-fatal errors relating to the Window manager. The errors generally occur after playing a game for 10 to 15 minutes, and stop after ±20 errors are generated. No negative side effects seem to pop up.

Errors look like this on the console:

pyrogenesis[36019] <Error>: kCGErrorTypeCheck: CGSDispatchDatagramsFromStream : Bad datagram type 50331648
pyrogenesis[36019] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
pyrogenesis[36019] <Error>: kCGErrorIllegalArgument: CGSGetPortStreamData
pyrogenesis[36019] <Error>: kCGErrorRangeCheck: CGSDispatchDatagramsFromStream : Preposterous datagram length 926941440
pyrogenesis[36019] <Error>: kCGErrorIllegalArgument: CGSGetPortStreamData
pyrogenesis[36019] <Error>: kCGErrorTypeCheck: CGSDispatchDatagramsFromStream : Bad datagram type 83886080

See also the discussion on this in the forum, in particular for gdb backtracing output and Myconid's response to that (short version here):

"It appears these aren't graphics-related errors, but event handling errors from the window manager. They seem to be caused by either SDL or OSX, not Pyrogenesis. – Why are these triggered by my changes? Good question, as there's nothing in my code that relates to event handling! The main difference from an event-handling perspective is that the drawing phase takes longer than before, so maybe this forces an unexpected SDL or OSX bug to the surface."

(hmm, I cannot edit the original text?) Myconid's response can be found here. The errors started after applying his patch of 2012-07-28 (posted here).

Is this reproducible with recent releases or in SVN?
