[Vm-dev] Memory leak in Windows clipboard handling

In sqWin32Window.c, function clipboardWriteFromAt
The line
/* allocate temporary storage and copy string (inserting Lfs) */
cvt = tmp = malloc(utf8Count+1);
cvt is not released before function returns.
Should be safe to do so after its use in
/* Convert data to Unicode UTF16. */
MultiByteToWideChar( CP_UTF8, 0, cvt, -1, out, wcharsNeeded );
To reproduce:
Write a large string in a workspace (say, 1MB of ascii chars), then repeatedly copy it.
Squeak.exe's memory usage will grow, not released when doing garbage collection.
Cheers,
Henry
