Talk about silly byte-shaving ... the "stock" value does not work on s390x,
and probably not on some other platforms either.  Knock it up to twice the
pre-5.0.33 value to have some margin for future changes in compiler, glibc,
etc.  Suspect this number if "execution_constants" regression test fails.
