I worked with I*M mainframe COBOL compilers where table misalignment 
caused memory corruption, with-out any compile or run-time warnings or 
errors.

For TC, I think the best approach would be a compile time traps for 
literals indexes which are out of range, and a run-time option 
(htrtconf) to deal with identifier indexes which are out of range.

I will try to add these features before the next TC release.
