TITLE   :FIX: F1001 or F1002 Compiling Program with Record Using -Zi
PRODUCT :Microsoft Fortran Compiler
PROD/VER::1.0,1.0a
OPER/SYS:
KEYWORDS:kberrmsg kbCompiler kbFL32 kbFortranPS

======================================================================
-------------------------------------------------------------------------------
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
========

Using FORTRAN PowerStation to compile a program containing records may
generate:

   fatal error F1002: compiler is out of heap space in pass 2

   -or-

   fatal error F1001: INTERNAL COMPILER ERROR
   (compiler file '@(#)p2symtab.c:1.89', line 1490)

The line number is 1279 when using FORTRAN PowerStation for MS-DOS.

CAUSE
=====

This error occurs only when using the -Zi compiler option, and is related to the
number of characters in the names of the structure members and the layout and
contents of the structure.

RESOLUTION
==========

There are three different ways to resolve these problems:

 - Reorder the structure. Putting small items first often eliminates both
   errors.

-or-

 - Use one-character-long member names.

-or-

 - Recompile without -Zi.

STATUS
======

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

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

Compiling the sample program with -Zi will generate the "F1002: compiler is out
of heap in pass 2" error.

Shortening "xY" to "Y" or increasing 60000 to 70000 causes the F1001 error.

Trimming "x" from "xY" and "xZ" or moving the 60000 element X array to the end of
the structure eliminates both problems.

Sample Code
-----------

   C Compile options needed: -Zi
         STRUCTURE /CBF/ 
           CHARACTER*1   X (60000)
           INTEGER*4     xY (4)
           CHARACTER*1   xZ (1)
         END STRUCTURE

         RECORD /CBF/ CB

         END
