> I found that when inserting a row that triggers a foreign key
> violation or duplicate row violation, freetds was unable to
> properly read all data from the wire.
> When such an aforementioned error is triggered the database
> sends a EED token which gets processed by tds_process_msg().
> When the status byte of the EED message is set to 1,
> additional error data follows; freetds fails to read this
> data from wire - which appears to let sqsh think it must read
> data and thus causing it to segfault.
> The attached patch fixes this bug; I'd be glad if it's not
> too late for the release...
> Greets from Karlsruhe,
this patch was included in 0.62 however I do not agree... the reason is
that tds_process_trailing_tokens all tokens till IDLE state so client do
not receive DONE token...
