in mysql_stmt_fetch_column function have follow code

    if (bind[0].length)

      *bind[0].length= stmt->bind[column].length_value;

    else

      *bind[0].length= *stmt->bind[column].length;

if bind[0].length ptr is NULL, else branch will coredump

The right code maybe

    if (bind[0].length)

      *bind[0].length= *stmt->bind[column].length;

    else

      bind[0].length= &stmt->bind[column].length_value;
