I use a "Power Mac G5", and "gfortran" compiler for my Fortran 90
codes. (The same compiler also compiles Fortran 95 and 03.)

Recently on two occasions, I attempted to treat the size of an array
as larger than it was defined at the beginning of my Fortran 90 code.
(This was a long code and was modified from an earlier one, and there
were many arrays whose sizes were defined by parameters given in the
same code, so the problem was not easily spotted simply by viewing the
source code.) In other words, it is like

..........................................
integer, parameter:: max=10
real:: a(max)

integer:: i

do i=1, 50
    a(i)=float(i)*100.0
enddo
..........................................

The problem is that the "gfortran" compiler does NOT give me any error
information, nor do I get any error message when I run the job. It is
only when I look at the output data files that I notice the messy and
apparently wrong results. It took me quite a few attempts to find out
the problem.

Has anyone had similar problems? Is there anyway to let the "gfortran"
compiler report this problem?

Thank you for reading and replying!
