-Uhmm, It's been a couple months since I wrestled with this ,
basically what you have to do is turn off the gp allocation when
compiling this your code. As far as I can tell gp allocation is
some fast memory scheme for allocating common blocks and
external/global variables ( fortran and C words for the same thing).
It forces all kinds of restraints on how you organize your common
blocks and you have to be alot less sloppy in your code ( i.e. common
blocks have to be declared exactly the same everywhere.) This is the
fortran standard I believe , but there is almost no large real code in
the world that lives up to it. I think the option that works for
fortran is :
-G0 -static
Anyway this solved my problem, now if you ever figuire out how to run
a code this large in the debugger let me know %-)!
