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]
