    Description

      Summary is pretty descriptive. The testcase
      ODBC_TEST(t_unbind_before_fetch)

      { SQLUINTEGER dummy; OK_SIMPLE_STMT(Stmt, "SELECT 1"); CHECK_STMT_RC(Stmt, SQLFreeStmt(Stmt, SQL_UNBIND)); CHECK_STMT_RC(Stmt, SQLBindCol(Stmt, 1, SQL_C_ULONG, &dummy, 0, NULL)); CHECK_STMT_RC(Stmt, SQLFetchScroll(Stmt, SQL_FETCH_NEXT, 1)); return OK; }

      Crash occurs in the call of SQLFetchScroll. Can be SQLFetch, as well.
      Affects (at least) Microsoft ODBC test tool. 2.0 doesn't seem to be vulnerable
