   1 ! { dg-do compile }
   2 ! Tests the fix for a further regression caused by the
   3 ! fix for PR28788, as noted in reply #9 in the Bugzilla
   4 ! entry by Martin Reinecke <martin@mpa-garching.mpg.de>.
   5 ! The problem was caused by certain types of references
   6 ! that point to a deleted derived type symbol, after the
   7 ! type has been associated to another namespace. An
   8 ! example of this is the specification expression for x
   9 ! in subroutine foo below.  At the same time, this tests
  10 ! the correct association of typeaa between a module
  11 ! procedure and a new definition of the type in MAIN.
