Perhaps, if the TDS protocol were open and Sybase invited all comers. But
Sybase doesn't support other libraries. If Sybase's own drivers don't
triggger the crash, then it's a failure of FreeTDS to be compatible. You can
define it as a server bug, and I might agree. It still has to be avoided if
it can't be fixed.

Yes but only needed by Bronze Age servers.

Quite so, and orthogonal. :-)

If no one's using 4.2, and we're not determined to fix it so it's safe, then
it's just a trap for new installations.
