[PATCH 0/1] MR4233: winmm: Fix pszSound allocation in PlaySound_Alloc().

[Paul Gofman (＠gofman)]

In general, ucrtbase allocation are used here (and later ucrtbase.free for freeing memory). RtlCreateUnicodeStringFromAsciiz() is using RtlAllocateHeap(GetProcessHeap(),...) for allocation. Using ucrtbase.free() may results in freeing from a different heap which leaks the string as best or aborts the program when heap validation is enabled.
