The GNU/Binutils nm command has the option, --demangle, which is useful.
Use this with both the shared library module, plugin.so, to determine
just what _ZN8RootClassC2Ev is (which constructor) and also do it on
Main as well (to determine just which constructors are defined).
There might be an 'implicit' constructor being used in your plugin, that
is in fact not defined elsewhere.
