Kunal,

I have verified that this simulation, when it is set up on a real
Linus workstation and run with the same parfile you used, does not
reproduce your problem.

I agree with Anshu that this is likely an issue with your libraries or
compiler configuration.

I assume you must have already modified the Makefile.h to suit your
machine?  (The version you get with your ./setup line is a copy of
sites/Prototypes/Linux/Makefile.h.pg, and it is unlikely that all the
paths in that version were correct for your machine.)  You could try
whether some of the compiler flags in that file causes problems,
in particular FFLAGS_OPT.

Have you tested your compiler installation at all with a simple test
FORTRAN program?  Maybe just a short main program calling a simple
subroutine, passing some double precision values, and checking that
values are as expected. You should first verify that you can compile,
build, and run this correctly.

Perhaps someone else, who already has experience with setting up FLASH
to run on a Windows platform (with Cygwin?), can help you more.
