Can anyone help plz:
My fortran77 code compiles & builds using default options with openf90 - the executable runs on my Athlon II but causes core dump with an illegal instruction
on my Opteron 248. Both systems are built with fedora c17 and are otherwise identically built - the opteron is clearly the old machine - but is
needed because it will be my main number cruncher. I have not found any suggestions on the blogosphere. I thought about trying to install
core dump and crash reporter but have no experience. Could anyone suggest what I might do to track down the problem and get up and running.
