Regression test looks right actually, the problem seems to be in custom verb
part:

---
    size = FIELD_OFFSET(BINDINFO, szCustomVerb)+sizeof(void*);
    if(pcbiSrc->cbSize>=size && pcbiDest->cbSize>=size &&
pcbiSrc->szCustomVerb) {
        size = (strlenW(pcbiSrc->szCustomVerb)+1)*sizeof(WCHAR);
        pcbiDest->szCustomVerb = CoTaskMemAlloc(size);
        if(!pcbiDest->szCustomVerb) {
            CoTaskMemFree(pcbiDest->szExtraInfo);
            ReleaseStgMedium(&pcbiDest->stgmedData);
            return E_OUTOFMEMORY;
        }
    }

it's never copied here, it worked before cause it was just a pointer copy.
