World querying issues using: void RayCast(b2RayCastCallback* callback, const b2Vec2& point1, const b2Vec2& point2);

GoogleCodeExporter commented 8 years ago

What steps will reproduce the problem?
1. Run the source code on the testbed

2. On my computer one the angles in which the raycast fails is "float 
currRayAngle =  2.078693". Please see attached code.

3.

What is the expected output? What do you see instead?
The ray should hit the box all the time, but it does it intermittently.

What version of the product are you using? On what operating system?
Box2D_v2.1.2 / LMDE 64bits / gcc (Debian 4.8.2-1) 4.8.2

Please provide any additional information below.
The attached code can be run on the testbed. This is a slightly modified 
version from:

Old version of Box2D. ReportFixture should return the fraction.
