如果存在 arangosearch 视图，ArangDb 3.4.milestone0 会崩溃

Question

尝试使用 ArangoSearch 的新功能时，我发现 "arangod" 崩溃了，"Segmentation fault"。这发生在两种情况下：

Collection 已经有一个 "arangosearch" 视图，我尝试通过 API;
如果数据已经加载，尝试创建视图会得到相同的结果，"Segmentation fault"。

我用 GDB 做了一个堆栈跟踪：

你能帮忙吗？两种方式的问题：无法在存在的视图中加载数据，或者如果加载数据则无法创建视图。结果相同：分段错误。任何建议表示赞赏。提前致谢！
