--- Comment #9 from Martin Sebor <msebor at gcc dot gnu.org> ---
This problem seems to have cleared up. GDB prints the correct file name and
line number, and I don't see any obvious problems in the line number program
emitted by GCC. I'm resolving this as fixed. Please reopen it if I missed
something and the problem still persists in some form.
