Hang on - are you saying that GDB alters the contents of the filename 
field inside the BFD structure ?  If so, then surely the correct thing 
to do now is to remove that piece of code from GDB.

I ran as many checks as I could and visually inspected all of the code. 
  I think that I found everywhere that the filename is touched.  At 
least inside the binutils that is.
