> MIMEHdr fails to find a MIMEField occasionally due to improper type conversion.
> It happens if the lower 32 bits of addresses of m_field_slots are the same. The logic below picks up wrong block.
> mime_hdr_field_slotnum(): 
> {code}
> for (fblock = &(mh->m_first_fblock); fblock != NULL; fblock = fblock->m_next) {
>     MIMEField *first = &(fblock->m_field_slots[0]);
>     int block_slot = (int)(field - first); // in units of MIMEField
>     if ((block_slot >= 0) && (block_slot < MIME_FIELD_BLOCK_SLOTS))
> {code}
> The type of block_slot should be intptr_t.
