Problem IT33715 Status: Closed

ASSERT FAILED SEGV TRYING TO EXECUTE PROCEDURE USING DRDA PROTOCOL WHEN
FUNCTION DOES NOT EXECUTE A RETURN STATEMENT

product:
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problem description:
On Linux x86-64 this was the stack trace seen from the
assertion:

The session was attempting to execute the following SQL:

Current SQL statement (0) :
  execute procedure decproc(261029770);


Here is the code for decproc, showing that it has no return
statement:

create function decproc (decarg dec(11,0))
returning smallint as retint;

define n_retint smallint;

let n_retint = 0;

end function;

The server has no problems doing the "execute procedure" call
when using the SQLI protocol.
