Yes, the bug is in rsaenh.c in the RSAENH_CPHashData() function at line 3959:

if (!get_algid_info(hProv, pCryptHash->aiAlgid) || pCryptHash->aiAlgid ==
CALG_SSL3_SHAMD5)
{
    SetLastError(NTE_BAD_ALGID);
    return FALSE;
}

This check forces an error, but why?  There is no comment or documentation on
why the Wine implementation does not support CALG_SSL3_SHAMD5.

Again, it can be confirmed that the Microsoft CryptSighHash function supports
this.
