This is the error that I am getting reported back to me by valgrind for my program. Unfortunately whatever the real reason is causing Valgrind to barf at this error and cry foul. The Valgrind FAQ says fix your memory errors and this will hopefully go away. Well I am quite naive on my use of Valgrind to nail down a particular bug. From the output below can anyone suggested as to where to start looking?
