Mplay32.exe Leaks Memory When Playing a MIDI File

ID: Q223774

The information in this article applies to:

Microsoft Windows NT Server version 4.0
Microsoft Windows NT Workstation version 4.0

SYMPTOMS

When you play MIDI files with the Windows Media Player (Mplay32.exe) and specify Auto Repeat and Rewind, a memory leak of 4 KB occurs for each play. A memory leak does not occur when playing wave files on Media Player.

CAUSE

This problem occurs because the pointer, which maintains memory addresses that saved 4 KB at the time the heap was allocated, performs heap allocation without releasing the heap and overwrites the pointer value.
