Comment:

 I've confirmed that this patch works and pushed it to master.

 Note that I did ''not'' include the change to configure.ac to set the
 -ftrapv flag, since there is a runtime cost. Probably the correct thing is
 to set up one of our build farm boxes to include the -ftrapv flag on build
 so that when tests are run this behavior is verified. (Ticket #3318
 documents this.)

 I have not added a !ChangeLog entry as this is entirely an internal
 change.
