["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Compile the following program with "gfortran -static -o adjustr adjustr.f90"
Then try to execute the generated binray.

  program test_adjustr
  implicit none
  character(len=10) s1, s2
       !0123456789
  s1 = 'Steve'
  s2 = adjustr(s1)
  print*, 's1          = "', s1, '"'
  print*, 'adjustr(s1) = "', s2, '"'
       !0123456789
  s1 = '  Steve'
  s2 = adjustr(s1)
  print*, 's1          = "', s1, '"'
  print*, 'adjustr(s1) = "', s2, '"'
       !0123456789
  s1 = '     Steve'
  s2 = adjustr(s1)
  print*, 's1          = "', s1, '"'
  print*, 'adjustr(s1) = "', s2, '"'

  end program test_adjustr
