broadPhaseNode crash

Postby misho » Fri Oct 19, 2018 5:44 pm

I am getting a crash in dgBroadPhaseMixed.cpp, line 381:

Code: Select all
         dgBroadPhaseNode* const broadPhaseNode = bodyArray[i].m_body->GetBroadPhase();
         dgAssert(broadPhaseNode->IsLeafNode());


In some instances it appears that broadPhaseNode is coming back as NULL, and it fails on the next line. I "patched" it by inserting

Code: Select all
         dgBroadPhaseNode* const broadPhaseNode = bodyArray[i].m_body->GetBroadPhase();
         if (!broadPhaseNode)
            continue;
         dgAssert(broadPhaseNode->IsLeafNode());


I know this is kludgy and this is a temporary fix, but it makes my code run fine. I have a Newton build from 10 days ago, and this started happening just a few days ago. I'm not sure if it is something I did since then, or I'm using my code in a way that would manifest this problem.

Any ideas what this may be?

the check will not fix it, some how you have a null body that should not be on that list.
I believe this was fixed few days ago, sync and it should be fine.
