--- Comment #1 from Tom Tromey <tromey at sourceware dot org> ---
I have a somewhat similar problem.

Suppose the user does 'file zzz', where zzz is a symlink.
Then, after running, the user resets the symlink to point to some
other file.

In this case, gdb won't change -- because the realpath'ing in
the objfile creation path will wind up resolving the symlink,
and so reread_symbols will think nothing has changed.

Locally this is complicated by the fact that we have a workaround
for the Windows gnulib/BFD stat mismatch bug in place.

I think my partial solution will be to remove OPF_RETURN_REALPATH
from symfile_bfd_open.

A full solution for this bug would probably involve storing the
user-specified name in the objfile and then changing various
spots in gdb to use that.  That is, the objfile would need one
name and the BFD would get another.
