SYMPTOMS
When you play MIDI files with the Microsoft 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.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
