Can one or both of you run that with valgrind to see whether it shows the root cause of the problem? It looks like there is some problem with the interpretation of the size of arguments passed to WindSearch(), maybe the size of ClientData? But I've never heard of that happening before (from the .dylib, I see you're on a Mac. . . there have been problems reported with the Mac depending on what source of Tcl/Tk you use, so that might be the issue here). @tnt: Are you also using a Mac?
