iTunes stopped working on windows 8 while closing the application

while closing itunes it stopped working unexpectedly, i faced this problem for more than couple of times. last time when i tried to debug it using microsoft visual studio I got a result like " Unhandled exception at 0x77D2A94F (ntdll.dll) in iTunes.exe: 0xC0000374: A heap has been corrupted (parameters: 0x77D3E1E8). " what may be the problem? and how can I fix it?
