* generic/tclInt.h (tclOriginalNotifier):
* generic/tclStubInit.c (tclOriginalNotifier): * mac/tclMacNotify.c (Tcl_SetTimer,Tcl_WaitForEvent): * unix/tclUnixNotfy.c (Tcl_SetTimer,Tcl_WaitForEvent, Tcl_CreateFileHandler,Tcl_DeleteFileHandler): * win/tclWinNotify.c (Tcl_SetTimer,Tcl_WaitForEvent): Some linkers apparently use a different representation for a pointer to a function within the same compilation unit and a pointer to a function in a different compilation unit. This causes checks like those in the original notifier procedures to fall into infinite loops. The fix is to store pointers to the original notifier procedures in a struct defined in the same compilation unit as the stubs tables, and compare against those values. [Bug 707174]
