  4.   dgInt32 faceOffsetHitogram[256];
  5.   dgSubMesh* mainSegmenst[256];
  6.   ...
  7.   memset(faceOffsetHitogram, 0, sizeof(faceOffsetHitogram));
  8.   memset(mainSegmenst, 0, sizeof(faceOffsetHitogram));
  9.   ...
  10. }
  11.  
  12. A 64-bit error. These are the consequences of Copy-Paste. In a 64-bit program, the pointer size will become non-equal to the dgint32 size and we will clear only a part of the mainSegmenst array.
  13.  
  14. This suspicious code was found in Newton Game Dynamics project by PVS-Studio static code analyzer.
  15. Warning message is:
  16. V512 A call of the 'memset' function will lead to a buffer overflow or underflow.  physics  dgcollisioncompoundbreakable.cpp  702
