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.
