Usually?
It's not "usually" erroneous, it's that virtfunc.cc is worst case.
In reality, it works most of the time.
This is why i haven't just disabled it. People would scream bloody

Like I said, i also have them all passing with the new abi, and as
soon as i get subobjects printing okay, i'll submit the patch.
