FIX: Upper Half of 32-bit Registers, GS, and FS Corrupt (87548)
The information in this article applies to:
- Microsoft CodeView for MS-DOS
- Microsoft CodeView for Windows
This article was previously published under Q87548 SYMPTOMS
When single-stepping or tracing through code in Microsoft CodeView versions
4.0, 4.01, and 4.05, the lower half of the 32-bit registers (eax, ebx, edi,
etc.) is always preserved, but the upper half may be corrupted. Other 386-
specific registers, such as the gs and fs registers, may also be corrupted.
This problem also occurs when animating. This problem does not occur if the
instructions are not executed one at a time.
STATUS
Microsoft has confirmed this to be a problem in CodeView version 4.0, 4.01,
and 4.05. This problem was corrected in CodeView version 4.1.
