>Release: FreeBSD 3.3-STABLE alpha
>Organization:
Lucky Net Ltd.
>Environment:
FreeBSD 3.3-STABLE on Alpha
>Description:
The following piece of mci_dump() uses bad conversion:
snprintf(p, SPACELEFT(buf, p), "MCI@%lx: ",
sizeof(void *) == sizeof(u_long) ?
(u_long)(void *)mci : (u_long)(u_int)(void *)mci);
On Alpha architecture, conversion from void* to u_int loses significant bits.
These conversions are FreeBSD-specific; original Allman's sendmail
does not contain them.
>How-To-Repeat:
Read and compile the code ;)
>Fix:
Convert to ptrdiff_t instead of u_int (?)
