In gcc4, operator new() is defined in <new> as visibilty("default").
If we override operator new(), our override gets exported; our

new() is called by the OS... With very bad results.
Please does anyone have any ideas how to make our operator new()
"hidden"?
If we set it in our source as hidden, then the compiler warns that the
attribute is ignored (since it was previously defined in <new> as
"default")
You can put this:
You can list a file such as unexported.exp in your "Unexported
Symbols File". That file should contain:
__Znwm
__Znwm.eh
__ZdlPv
__ZdlPv.eh
Alternatively, you can create a file registered with "Exported
Symbols File" which does not contain the above symbols.
If you're working from the command line, the flags are:
-unexported_symbols_list <filename>
-exported_symbols_list <filename>
