Description soldatov 2012-06-18 09:10:13 UTC 
Static code analyzer speaks about error at 198th line in traffic.cc:
ERROR: ABR beyond Array Bounds Read  lanes[__1fPtraffic_advance6F_v1BBj_+1] in traffic.cc with 7051 offset

original code:
List *upperlane = IsLowerLane(j) ? lanes[LowerToUpperLane(j)] : NULL;
code in macro expansion tab:
List *upperlane = (! (( j ) & 1) ) ? lanes[(( j )+1)] : 0;

It's a false positive error.
To avoid this error select Tools->Options->Editor->Hints->C/C++ Source Files->Static Code Analyzer->Confidence = Sure.
