I try to execute some code:
{ok, Conn} = odbc:connect("user/pass@REDACTED", [{scrollable_cursors, off}, {auto_commit, on}, {binary_strings, on}]).
odbc:param_query (Conn, "begin ? := null; end;", [{{sql_varchar, 8000}, out, [<<"">>]}]).

And odbcserver crashes...
ODBC: received unexpected info: {tcp_closed,#Port<0.4260>}

Why odbcserver crashes on binding NULL value into varchar output parameter?
