It's SIC.
"NETRootInfo(connection, properties, 1);" would now cause an error, but since it's been buggy anyway (enums are indeed not polymorphic, but for int,... though gcc could have known better) that should hardly matter.

@Marco
got that with gcc or clang? And which version and what specific call?
The constructor is (theoretically) correctly resolvable and if it's an ambiguous call, i'd expect a compiler error as well...
