      The Table-Driven C++ Exception Handling (TDEH) code in the Run-Time Support library (RTS) had a bug where it could read past the end of the EXIDX section when handling a C++ exception. This could cause a bogus, unpredictable result when handling an exception, and it could result in a read outside of configured memory. This bug can only happen in C++, and only when an exception is thrown by the program.
