Q87544: FIX: "Application Error" When HEAPSIZE MAXVAL in .DEF File

Article: Q87544
Product(s): Microsoft Programming Utilities

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

- Microsoft LINK for MS-DOS, versions 5.0x, 5.1x, 5.2, 5.3x, 5.5 
- Microsoft LINK for OS/2, versions 5.0x, 5.1, 5.11, 5.13, 5.15, 5.31 
-------------------------------------------------------------------------------

SYMPTOMS
========

In Microsoft Windows version 3.1, an attempt to run an application linked with
Microsoft LINK fails and Windows displays the following message:

  Application Execution Error

  Insufficient memory to run this application. Quit one or more Windows
  Applications and then try again.

In Windows version 3.0, an attempt to run the application causes the computer to
hang.

CAUSE
=====

The module-definition (.DEF) file for the application contains a HEAPSIZE MAXVAL
statement. The error occurs because the data segment is 64K; Windows requires 16
free bytes in each application's data segment.

RESOLUTION
==========

Modify the module-definition file such that the value specified for the HEAPSIZE
added to the size of the DGROUP segment is no larger than 64K - 16 bytes.

STATUS
======

Microsoft has confirmed this to be a problem in LINK versions 5.3, 5.31.009, and
5.5 for MS-DOS and version 5.31 for OS/2. This problem was corrected in LINK for
MS-DOS version 5.6.

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

HEAPSIZE MAXVAL sets the heap size to 64K minus the size of DGROUP. This does
not leave the required 16 bytes free.
