With the information you have given us, all I can say is that GDB
should be able to handle the situation, so we do have a bug somewhere.
Whether it is in GCC or GDB is still an open question as far as I can
tell.

Have you checked the line-table as well in both cases? There is
a very convenient command that gives you the list of lines known
by GDB for any given file: -symbol-list-lines. It's a MI command,
but you should be able to use it from the GDB prompt using
"interpreter-exe mi -symbol-list-lines" followed by the filename.
