I don't think it would do that in release mode. However, in debug
there are several things going on with the VC C++ compiler. I
haven't checked if it patterns malloc/free memory but it
certainly patterns the stack memory and puts variables apart with
guard patterns in between. Upon function/frame exit it checks all
this. This is dog slow but very useful and I have found many bugs
thanks to this. This of course will be unacceptable in a release
build. Also initialize malloc/free with pattern would be
undesirable in a release build.
