I agree with your analysis.  I found PR 31154 after I posted the
code.  BTW, I posted a call for real-world codes using ICB on
comp.lang.fortran.  I've gotten a few responses so I trying to
break your patch :-)

One response stated:

   I hope gfortran implementation of ISO_C_BINDING permits the use of
   private components in a derived type with BIND(C) attribute (to my
   best knowledge g95 doesn't ).

   In a recent discussion, Richard Maine clarified that

   "a derived type with the BIND(C) attribute"

   1) is allowed to be a "PRIVATE type" and/or
   2) is allowed to be a type with "PRIVATE" components.

   The second one is used in the above Pthread Interface implementation
   (which makes perfect sense).

I checked your testsuite codes (with a quick glance) and could not
find anything that matches this description.  Should we add a few
more tests?
