Subject: 23.1.50; gdb-mi does "list :1" and gets "No source file named ." on
         installed executables
Date: Mon, 27 Jul 2009 15:01:02 +0100

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug <at> gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I have an executable compiled with -g and installed (copied to some
other directory, or just to another name).  gdb run by hand is fine with
debugging the installed file, and gdb-mi shows the source correctly (so
it's finding the source files fine), but something goes wrong in gdb-mi:

    (gdb) break main
    Breakpoint 1 at 0x80483fd: file test/hello.c, line 7.
    (gdb) list :1
    No source file named .

and subsequent commands all get the same error.  I presume this is
happening in gdb-place-breakpoints, where gdb-location-alist seems
always to be nil (I guess it should not be).

Everything works fine with the original executable.
