Q111283: FIX: F1001 Error Compiling 2 Gigabyte Array with -Zi

Article: Q111283
Product(s): Microsoft Fortran Compiler
Version(s): 1.0,1.0a
Operating System(s): 
Keyword(s): kberrmsg kbCompiler kbFL32 kbFortranPS
Last Modified: 24-MAR-2000

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft FORTRAN PowerStation for MS-DOS, versions 1.0, 1.0a 
- Microsoft Fortran Powerstation 32 for Windows NT, version 1.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Compiling a FORTRAN source file with -Zi that contains a 2 gigabyte (GB) array
(or larger) will produce the following error under Windows NT:

  fatal error F1001: INTERNAL COMPILER ERROR
  (compiler file '@(#)p2symtab.c:1.89', line 1601)

Under MS-DOS, the following error may be generated:

  fatal error F1001: INTERNAL COMPILER ERROR
  (compiler file '@(#)p2symtab.c:1.89', line 1390)

CAUSE
=====

Although a Windows NT application has a 4 GB address space, 2 of these 4 GB are
reserved for system memory. Because a 2 GB array leaves no room for application
code, this particular condition was not tested.

RESOLUTION
==========

Reduce the size of the array.

NOTE: Linking a Fortran object module that contains an array 2 gigabytes (or
greater) will correctly cause the following warning message under Fortran
PowerStation 4.0:

  :warning LNK4084: total image size -2147422208 exceeds max
  (268435456); image may not run

STATUS
======

Microsoft has confirmed this to be a problem in FORTRAN PowerStation 32 for
Windows NT version 1.0 and MS-DOS version 1.0 and 1.0a. This problem was
corrected in FORTRAN PowerStation 32, version 4.0.

MORE INFORMATION
================

The following sample illustrates the problem:

Sample Code
