--- Comment #7 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
I think the problem never really went away, but it was simply not seen on most
targets. It has reappeared on aarch64-darwin, and was painful to chase down:

Hopefully, Chris' patch fixed this bug.  If problems
re-appear we can also re-open the PR.

The test case is still not working for me on IA64 HP-UX.  I also still see
gfortran.dg/c_kind_params.f90 failing at all optimization levels. 
c_char_tests.f03 also fails

FIXED. Steve, please check under IA64 HP-UX whether it works now.
