#14 No error exit on 'server is terminating this process'

[Ed Avis]

I have some SQL which sometimes triggers a Sybase bug
and 'The SQL server is terminating this process'. I
see the same problem using both sqsh and DBD::Sybase.
But sqsh does not correctly report the failure in its
exit status; it still exits with a true value even
though it did print the message.

I don't have any .sqshrc file so I think I am getting
the default error handling. Surely 'terminating this
process' has a higher severity than the default
threshold for exiting with failure?
