The information in this article applies to:
- Microsoft Macro Assembler (MASM), versions 6.0, 6.0a, 6.0b
-------------------------------------------------------------------------------
SYMPTOMS
========
When using Microsoft Macro Assembler version 6.0, 6.0a, or 6.0b to assemble a
program that has a large structure, specifying CodeView information with the /Zi
switch on the assembler and the /CO switch on the linker may cause the following
linker error:
fatal error L1057: data record too large
CAUSE
=====
MASM generates an incorrect LEDATA record when the source code declares large
data structures.
RESOLUTION
==========
Reducing the length of one of the longer field names in the structure will
eliminate the error.
STATUS
======
Microsoft has confirmed this to be a problem in MASM versions 6.0, 6.0a, and
6.0b. This problem was corrected in MASM for MS-DOS version 6.1.
MORE INFORMATION
================
The following sample code demonstrates the problem. Reducing the length of one
of the longer field names eliminates the error.
