PRB: Segment Was Discardable Under 3.0 Notification

ID: Q81546

The information in this article applies to:

Microsoft Windows Software Development Kit (SDK) 3.1

SYMPTOMS

The debugging version of Microsoft Windows version 3.1 writes the following notification to the debugging terminal:

Segment was discardable under 3.0

CAUSE

One or more code segments of a dynamic-link library (DLL) are marked MOVEABLE and are not marked DISCARDABLE.

RESOLUTION

Modify the module definition (.DEF) file for the DLL to mark all MOVEABLE code segments as DISCARDABLE.

MORE INFORMATION

Under Windows version 3.0, MOVEABLE code segments in a DLL are DISCARDABLE by default. This behavior changes under Windows 3.1; segments must be marked DISCARDABLE to be discarded. The debug notification highlights the change in behavior between the two versions of Windows.
