There is this annyoing weirdness in Sybase. Better to have it read by people and spidered by Google than not, so here it is.
If you, in a stored procedure, have an output parameter of type bit and it doesn't have a value (it may be passed in with a NULL value) when the procedure returns, the ct-lib on the client will crash due to faulty TDS data.
This can happen if e.g. a foreign key constraint is violated and an error is raised before you touch the variable.
The solution is to make sure the variable always has a proper bit-like value, so put
select @is_weird = 1
at the beginning of the procedure before anyhing can go wrong.
