Errors while running CTest



It looks like a t64 (2038) error.  It's testing for timestamp 2038
which is out of bounds on a 32-bit time count. In that case perhaps
the Timestamp2038 test should be skipped on 32-bit systems.

On the other hand the RunCMake.string test is passing on other 32-bit
systems, armhf, powerpc. What is i386 doing differently with respect
to this test compared to the other 32-bit architectures?
