The problem appears to be restricted only to procedures with output 
parameters.  We have not encountered the problem with any procedure that only 
has input parameters.

We can only avoid the problem by either not using 'SET NOCOUNT ON' or moving 
'SET NOCOUNT ON' to a later point in the procedure.  This is demonstrated by 
the different examples in the test case.  Also note that having output 
parameters and 'SET NOCOUNT ON' as the first statement does not guarantee 
failure as shown with the example that begins with print "\nCreate $proc with 
input, output, select, init SET NOCOUNT\n";

Please let me know if you need more information.

Is the problem restricted to procedures that pass parameters?  If not,
does bsqldb exhibit the same symptoms?  If so, could you provide just
the SQL?  

If parameters are required to provoke the problem, I would alter
src/odbc/unittests/rpc.c to induce it.  It tried the attached patch;
it did not alter the outcome of the test.  

HTH.
