You need the functionality of "nothrow new" in the C++ standard. Syntax is something like the following... #include <new> ptr2object = new(std::nothrow) ClassType( ... ) ; I'm not sure of what g++ provides, and my installation is hosed at the moment (so I can't test this), but gcc is pretty compliant and up-to-date. I'd be surprised if it didn't have nothrow new... However, I do not know if there is a way to get similar functionality without modifying code (calls to new). Hope this helps, Michael
