  14 * The following bug is in all snapshots starting
  15 * from April 18.  I have only tested this on Alpha linux,
  16 * and with FFECOM_FASTER_ARRAY_REFS set to 1.
  17 *
  18 * Run the following through g77:
  19 *
  20       subroutine a
  21       character*2 string1
  22       character*2 string2
  23       character*4 string3
  24       string1 = 's1'
  25       string2 = 's2'
  26 c
  27 c the next 2 lines are ok.
  28       string3 = (string1 // string2)
  29       call b(string1//string2)
  30 c
  31 c this line gives gcc/f/com.c:10660: failed assertion `hook'
  32       call b((string1//string2))
  33       end
  34 *
