Crash calling a function via ODBC

Finally I could succesfully call a postgres function via odbc using the
syntax:

{? = CALL myFunc(?, ?)}

My func uses SQLBindParameter and SQLExecDirect
All works ok and I succesfully get input and output parameters, great!

BUT
If I remove the {} around from the sql string the driver crashes (in
SQLExecDirect) !!
I'm using:
/usr/local/pgsql/lib/libpsqlodbc.so.0.27
