f77 bug on IRIX 3.2

[John H Merritt]

Here's something that fails to produce correct output.
When you use a temporary variable for c_ext (or the string),
in the concatination statement, you get the correct result.

      program ch
      character c_ext*16, filename*7

      filename = 'FOO.BAR'
      c_ext = '.2'
      c_ext = filename // c_ext

      print*,'c_ext:',c_ext

      stop
      end

Produces:
 c_ext:FOO.BARFOO.BAR


I remember a bug when using  //  to create a filename in an open statement.
Is this the same bug?
