Fix for PR/39548

[Xinliang David Li]

This is the new version of the change -- the check is moved out of the
loop. I did not add the assertion in set_copy_of_val as this ended up
with lots of failures in regression test. May need investitagion
separately (real problem or interface design issue).

compiler bootstrapped on linux/i686. Regression test is redone.

Ok to checkin?
