visual c++ - VC++ EXE standalone has bugs that don't happen in IDE -

my program has specific error took me while track down - don't know how fix it. code long , in many files , don't see point in posting here.

in ide, runs fine, in both debug , release (with runtime library set either /mtd or /mt, respectively, i'm assuming dependencies included).

however, when run standalone, crash. @ first thought dependency problem doesn't seem so.

at point in code, accessing vector via method call: t->getlist(), getlist defined std::vector<t*> & getlist() , method returns member variable (simply defined std::vector<t*> field in class).

it turns out, if print out size of list while running ide, 0 (which correct answer in case).

however, when doing same thing running standalone, size 467467353.

i tried changing method declaration std::vector<t*> * getlist() , doing return &field; , updating rest of code didn't fix anything.

i tried replacing member variable field pointer, , in constructor instantiating new vector , deleting in destructor. still no luck.

so made simple test case program made class vector field, , method return reference it. in main create instance variable , getting vector , printing size. worked both in vc++ , standalone - both returned zero.

this driving me nuts , can't figure out why i'm getting different behaviour. why standalone running differently, , should looking @ fix this?

thanks

okay literally bug in code hidden. dynamically casting wrong type.

somehow slipped past when running on windows , osx in both debug , release, , standalone on osx. thing found it.
