Question

PVD版本：3.2019.04.26214843 Physx版本：3.4 我使用下面的界面在场景中查找重叠的实例。当没有连接DVD时，它可以正常工作。

virtual bool PxScene::overlap   (   const PxGeometry &  geometry,
        const PxTransform & pose,
        PxOverlapCallback & hitCall,
        const PxQueryFilterData &   filterData = PxQueryFilterData(),
        PxQueryFilterCallback * filterCall = NULL
    )

但是当我想用pvd检查重叠框时，在我使用此接口时它崩溃了，下面是堆栈跟踪。不知道这怎么会发生。熟悉pvd信息收集机制的任何人都可以给我一些建议，谢谢。

程序以信号SIGSEGV终止，出现分段错误。

一些变种信息

在场景中添加场景查询时，PVD崩溃
