  If you will look in the "log" file it contains the results of
  both uname -a and gfortran -v. It says

    gcc version 4.3.0 20070104 (experimental)

  I tried the above, but did not get any trace. Message said no stack.

  I have no idea if this is an old or a new problem. I am mostly using
  4.1 on solaris, linux, and mac (power pc). This is the first time 
  I have seen the problem.

  If it helps, I got around the problem by making the code from line
  105 to 117 into a subroutine. Also, the problem does not exist without
  -O3.

  Sorry I could not be of more help,

  Ray
