ID Number: Q76951

Summary:

PROBLEM ID: WIN9110002

SYMPTOMS

When using CodeView for Windows (CVW) to debug an application that

makes certain calls to the Windows GDI, CVW reports "Trap 0 -

divide overflow" and halts.

CAUSE

GDI installs its own trap 0 (zero) handler for speed reasons.

However, CVW ignores trap 0 handlers and always traps divide

overflows.

STATUS

Microsoft has confirmed this to be a problem with the Windows

Software Development Kit version 3.0. We are researching this

problem and will post more information here as it becomes

available.
