+! { dg-do run }
+! Tests the fix for PR27269 and PR27xxx.
+! The former caused a segfault in trying to process
+! module b, with an unused equivalence in a. The latter
+! produced an assembler error due to multiple declarations
+! for a module equivalence, when one of the variables was
+! initialized, as M in module a.
+!
+module a
+  integer, parameter :: dp = selected_real_kind (10)
+  real(dp) :: reM, M = 1.77d0
+  equivalence (M, reM)
+end module a
+
+module b
+  use a, only : dp
+end module b
+
+  use a
+  use b
+  if (reM .ne. 1.77d0) call abort ()
+  reM = 0.57d1
+  if (M .ne. 0.57d1) call abort ()
