What the hell.  Ok, the error makes sense since it's static analysis there.  May I inquire your build environment?  Happy to find a resolution for you but I need to be able to reproduce first.  And given ./configure; make; make that ain't happening.

That is actually a very good analysis though, either way, I get that it's an issue, but why use member.argv[0] here instead of member.subnames[0]?  Suspect this is where the other more complicated patch was probably better.
