passing std::map from one dll to another

[Carlos]

Hello!

I've run in a serious problem while I tried to pass an std::map from one DLL to another as a reference.
Let's call them DLL1 and DLL2.
DLL1 is calling function func( (std::map*)& map_in ) from DLL2, passing to the function an std::map as reference

func( map_in );

When the finction from DLL2 tries to iterate through the received map values, comes an "Access violation"!

Apparently, there are two static members in the _Tr member (type _Tree): _Nil es _Nilref, and these are different in the two DLL-s... ?

Any ideas? Is this a known problem?

Thank you very much! So, the static members were the problem!
