Crash in AllBulletDemos due to calling delete on non-heap variables. #608

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago

The CcdPhysicsDemo uses a global static variable:
static GLDebugDrawer sDebugDrawer
m_dynamicsWorld->setDebugDrawer(&sDebugDrawer);

In AllBulletDemos/Main.cpp, line #343 leads to a crash:
delete demo->getDynamicsWorld()->getDebugDrawer();

At least one other demo does this as well:
ConcaveRaycastDemo.cpp

Even though CreatDemo() allocates a new GLDebugDrawer() for each demo, 
CcdPhysicsDemo::initPhysics() may reset this to the static sDebugDrawer.

Changed state: Fixed

Strange, it didn't crash here so I didn't ran into it but it was surely wrong.

Fixed in latest trunk, thanks for the report!
