error with stl push_front in release version only

[jennyy]

Does anyone have any ideas about what's causing the following behavior? When I run my code that includes an stl list push_front in debug mode, it runs fine. When I create a release version with partial debugging enabled, and run with my program with the .net option "start" it runs fine. But when I run the program via "start without debugging" the release version, it breaks. When I run it with a release version with no debugging enabled at all, it breaks. The break occurs directly after the list push_front (but only on some executions of this command and not others)--i.e. sometimes push_front works and other times I can print out my list before the push_front, but if i try and print out my list after the push_front I get all kinds of problems with referencing null pointers or unintialized data. These errors do not occur with the item that i am pushing on to the list--rather the errors occur usually on the 4th or 5th element in the list (though I have had them occur on the 2nd element too). I can't figure out what i'm doing wrong. I belive that my copy constructors are correct, and even so I can't figure out why push front would modify elements in the middle of the list anyways. DOES ANYONE KNOW WHAT COULD BE CAUSING THIS?
