Assembler error - large data set.


Hello,

I need to write a program that reads a very large data file and I am getting a strange assembler error. It's clearly to do with the size of my data. I have written a toy program that illustrates the error:


program test use iso_fortran_env, only : real64

implicit none

    integer, parameter :: nrows = 233280000
    integer, parameter :: rp = real64

real(rp), dimension(nrows) :: longitude, latitude, height, area

    area = 0
    height = 0
    latitude = 0
    longitude = 0
end program


When I compile I get this:


gfortran -o test.o -c --std=f2008 -fimplicit-none -Wall -fbounds-check test.f90
/tmp/ccKqApNC.s: Assembler messages:
/tmp/ccKqApNC.s:31: Error: value of 000000014db5b000 too large for field of 4 bytes at 0000000000000061



Almost any change to the program will make the error go way. For example, if I have fewer variables, or if I use "real" instead of "real(rp)".


I don't know what to make of this and I'm hoping that someone can help me out.

Cheers,
Daniel.
