I believe the fix to PR47850 has resolved this issue. I suggest we close this
one.

I agree unless someone comes with an explicit example.

------- Comment #3 from jvdelisle at gcc dot gnu dot org 2009-12-05 04:17 -------
Studying this with a little instrumentation, I see that gfc_expand_constructor
is called only once with some of the test cases for pr20923. This is good.
Also, in the test case for pr41807, the work function constant_element does
nothing but check that the element is constant. In the patch for pr20923 I
will submit shortly, I have renamed it to is_constant_element which is clearer.
Moving on, the is_constant_element work function and the other constructor work
functions are called by expand_constructor. expand_constructor calls
gfc_simplify_expr. It is possible that gfc_simplify_expr is called more than
once on a given constructor expr as the various work functions are exercised. I
have not confirmed this. I wonder if it would make sense to add a flag to
gfc_expr to mark it as having been simplified already and do an early exit from
it for efficiency.
I will do some testing to see if it is indeed being called more than once and
report back.

Jerry, this might be involved in PR41165 as well?!

I plan to keep poking at this and other general constructor issues.
