Stack overwrite in b2CollidePolygons

No steps, sorry. One time exception in release mode, so I don't even know what
input data was.
All I know is that I've got stack overwrite in b2CollidePolygons.
The only way this could happen is if b2ClipSegmentToLine overwrote vOut[2] with
three elements. While not possible with regular numbers, maybe some combination
(NaN? Inf?) can lead to three elements being inserted into vOut...
Another possibility is to blame compiler optimizations that use SSE2 for
floating point operations.
Using Box2D 2.2.1 (official). OS Win 8 x64. VS2012 Compiler injected security
measure (a cookie) looking for stack overwrites. It detected a problem and
invoked __report_gsfailure which I guess terminates app.

Not much to go on here. Be sure b2_maxPolygonVertices is not exceeded. Also,
try running the trunk (pre-2.3).
