Esme Povirk (@madewokherd) commented about dlls/ole32/tests/ole2.c:
{ hdc = GetDC(NULL); data_size = GetWinMetaFileBits(stg_med->hEnhMetaFile, 0, NULL, MM_ANISOTROPIC, hdc);
data = HeapAlloc(GetProcessHeap(), 0, data_size);
data = malloc(data_size);
I can't find all the corresponding `free` calls for the `malloc` calls in `get_stgdef`, I think `test_OleCreateStaticFromData` might be leaking the data.
