The following gives the wrong answers.  It may have to do
with broadcasting things to arrays.  The all scalar case works
and an array first argument works.

      program FA1031

! fails on Windows XP
! gcc version 4.4.0 20080312 (experimental) [trunk revision 133139]

      INTEGER IDA1(10)
      LOGICAL GDA1(10)

      IDA1   = 0
      gda1 = (/ (i/2*2 .ne. I, i=1,10) /)
      print '(10L2)', gda1

      IDA1 = INDEX ( 'DEFDEF' , 'DEF', GDA1 )    !fails
      print '(10I2)', ida1

      IDA1 = INDEX ( (/ ('DEFDEF',i=1,10) /) , 'DEF', GDA1 )    !works
      print '(10I2)', ida1

      IDA = INDEX ( 'DEFDEF' , 'DEF', .true. )   !works
      print '(I2)', ida

      END
