That is the internal name of the function (it demangles to ABC::ABC() anyways)
and the symbol does not need to be in the symbol table at all.

We are going to run into this more with ICF also.  I think there might have
been a RFC about how to handle the debugging for commoning of functions but it
might be a while before that is implemented.
