[Message part 1 (text/plain, inline)]

Yes, sorry. I discovered that I looked at an old version. The latest git
version indeed allows disabling the -file-list-exec-source-files. I will
use that option which indeed is a work around for the problem.

In addition, I filed a bug for gdb that it should uniq the filenames output
by -file-list-exec-source-files.

I realized that all filelist-exec-source-files is used for is to turn on
gdb minor mode for all files that are currently open in emacs. Perhaps we
should turn the problem around by asking for a gdb function that answers
the question whether a file is referenced by an executable. It would then
be possible to loop over the emacs buffers and turn on gdb minor mode if
the file is referenced by the new gdb session.

Regards,
Dov
