[Valgrind-users] Pointer check with FORTRAN

[Federico G. A. <fed...@gm...>]

HI!

I've a simple FORTRAN code that does some operation (no more than addition
and multiplication) with complex number.

I've compiled my code with the -g option and with the -o3. And some of the
resulting values are different.
So I started inserting some WRITE statements in the intermediate computation
and some of the previous results that were different now are exactly the
same!!

I believe that this looks like a illegal value access problem, like reading
uninitialized variables, reading over arrays boundary.

I run the program under Valgrind with mem-check tool and it didn't find any
errors.
I run the program under Valgrind with pointer-check tool and it gives me a
lot of "Invalid read" messages at lines where OPEN, READ, WRITE function are
used.

What can I do?

thank you very much !

Federico
