hi,您好! 我在尝试使用"Greenplum roaring bitmap与业务场景 (类阿里云RDS PG varbitx, 应用于海量用户 实时画像和圈选、透视)"文章提到的方法优化查询时,Master 执行PREFUNC时,遇到了一个段错误,定位到代码错误位置在如下代码:
// Is the second argument non-null? if (!PG_ARGISNULL(1)) {
**r2 = (roaring_bitmap_t *) PG_GETARG_POINTER(1);** if (PG_ARGISNULL(0)) { r1 = roaring_bitmap_copy(r2); } else { roaring_bitmap_and_inplace(r1, r2); } roaring_bitmap_free(r2); }
其中获取的变量 r2 在使用时,会引起段错误,猜想是内存访问越界或者内存数据结构错误导致的,我使用的 Greenplum 版本是 5.11.1 PostgreSQL 8.3 。 您遇到过这样的问题么?
