FIX: Mixing \ and / in Command Line Causes Problems (34500)

The information in this article applies to:

Microsoft Macro Assembler (MASM) 5.1

This article was previously published under Q34500

SYMPTOMS

When mixing \ and / on the MASM command line, MASM will sometimes give incorrect results and hang. The following command line causes these problems:

   masm -I\sl200qr\sl -Mx -DVERS_DDQR -I\sl200qr/sl/cmerge/src/Common
    \sl200qr/sl/cmerge/src/Common/comsup.asm;

The option -Mx will be ignored. MASM also hangs when processing some assembler files.

CAUSE

In this case, MASM was incorrectly extracting the base name; it wrote the full path into an array big enough only for an 8.3 filename, thus overwriting many global flags.

STATUS

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