FIX: MASM 5.1/5.1a .OBJ May Cause LINK to Generate L2013 Error

• Microsoft Macro Assembler for MS-DOS, versions 5.1, 5.1a
• Microsoft Macro Assembler for OS/2, versions 5.1, 5.1a

SYMPTOMS

The Microsoft Macro Assembler (MASM) versions 5.1 and 5.1a may create an object file that cannot be linked properly with LINK because of an LIDATA record that is too large for LINK to handle. In this case, the following LINK error will be generated:

error L2013: LIDATA record too large

CAUSE

The problem results from the fact that MASM may generate an LIDATA record up to 1K in size, which is valid for LIDATA records in the Intel Object Module Format, but LINK will only accept LIDATA records that are 512 bytes or less. There is nothing actually wrong with the code generated by MASM except for the fact that it may contain an object module record that exceeds a documented limitation of LINK.

RESOLUTION

In MASM version 6.0, the assembler automatically corrects for this situation by creating multiple LIDATA records as necessary so that none exceed 512 bytes.

STATUS

Microsoft has confirmed this to be a problem in MASM versions 5.1 and 5.1a. This problem was corrected in MASM version 6.0.

MORE INFORMATION

The sample code below demonstrates this problem. While MASM 5.1 and 5.1a will correctly assemble the code, the object file created will cause the following error when linked:

error L2013: LIDATA record too large pos: 29E Record type: A2
