++ Subject: [PATCH] PhysX: Initialize the contact stream iterator without patches
++
++ PxContactStreamIterator leaves its patch, contact and face index pointers
++ uninitialized when constructed from a null patch stream, and its
++ hasNextPatch() only looks at the patch count, so a caller that trusts the
++ count can read them. GCC also sees this through the inlining and reports
++ it as a maybe-uninitialized use in code that includes the header with
++ warnings as errors.
++
++ This is the PhysX 4.1 patch "Workaround maybe-uninitialized error in GCC
++ 12.2.1", forward ported to 5.9.0, where PxContact.h is unchanged in this
++ respect.
++
++ Task-number: QTBUG-108045
