The above bug is exactly the same as mine. I'm using a library that's only available in 1 form. I'm not sure whether _SECURE_SCL is 0 or 1 in the library, is there any way to tell?

Either way, I'm getting internal errors in vectors, even those declared on the stack.

Any known STL bugs with _SECURE_SCL=0?

Visual Studio 2005 ( no service pack applied...)

I have recompiled all my C++ release build with _SECURE_SCL=0. I am getting access violations when iterating on a std::set with a custom "Compare". I use various STL classes throughout my code and this access violation happens only on this std::set with the custom compare function ( and _SECURE_SCL=0)

The application passes QA with _SECURE_SCL=1 in both Debug and Release mode. I can almost be 100% sure all my code that uses this set class has _SECURE_SCL=0 defined as I wrap std::set in a thin layer in my own header where I can #error if _SECURE_SCL!=0

One Definition Rule

When setting _SECURE_SCL=0, one must be careful to rebuild all (third party) libraries.

Otherwise, the linked program may contain several definitions of the same functions; some using _SECURE_SCL=1, some _SECURE_SCL=0. The compiler/linker does not diagnose this. The resulting executable will contain undefined behavior, which obviously may lead to all sorts of interesting situations (e.g. crashes in our case).

One more issue is that many vendors only provide their libraries compiled with one set of settings (either with _SECURE_SCL 0 or 1). You have to check which one, and if you have builds needing the other, build the library yourself and adjust your build settings to use the correct libraries.

About my comments of _SECURE_SCL vs. hash_map vs. std::list... I got feedback here internally that the problem only appears if one std::swap() two hash_maps. I've yet to confirm this, but it may point to something for you.
