   1 ! This testcase was miscompiled, because ts.cl
   2 ! in function bar was initially shared between both
   3 ! dummy arguments.  Although it was later unshared,
   4 ! all expressions which copied ts.cl from bar2
   5 ! before that used incorrectly bar1's length
   6 ! instead of bar2.
   7 ! { dg-do run }
