   1 ! { dg-do run }
   2 ! Tests the fix for PR27269 and PR27xxx.
   3 ! The former caused a segfault in trying to process
   4 ! module b, with an unused equivalence in a. The latter
   5 ! produced an assembler error due to multiple declarations
   6 ! for a module equivalence, when one of the variables was
   7 ! initialized, as M in module a.
