Somehow, I've missed that bug report :-( I have no objection to apply the patch, but wouldn't it be better to understand, why bindat-get-field returns file names like /ssh:vagrant@debug:/vagrant/"/vagrant/hello.c" ? Just patching the obscure result doesn't look error prone to me. Furthermore, - (setq f (concat (or (file-remote-p default-directory) "") f)) + (unless (file-remote-p f) + (setq f (concat (or (file-remote-p default-directory) "") f))) could be simplified to (setq f (concat (file-remote-p default-directory) f)) Best regards, Michael.

Setting breakpoints with C-x C-a C-b should work now The changes in ~gdb-mi.el~ fix the problem with the "no longer exist" error message. The change in ~gud.el~ makes the fringe mark work a bit better and also the source buffer to pop up when a break point is hit. The problem seems to be that not all filename information goes through (gdb-jsonify-buffer) but gdb-mi.el and gud.el read them directly from gdb's buffers. These patches check wheter a gdb buffer is remote, and wrap the file names accordingly. There is probably a better way to fix the problem, but my knowledge of gdb-mi.el is limited. Relates to bug #23608. *** Affected functions (gdb-place-breakpoints) (gdb-get-location) (gdb-goto-breakpoint) (gdb-frame-handler) (gud-file-name) *** References - https://debbugs.gnu.org/cgi/bugreport.cgi?bug=23608 --000000000000bab897059db0a146 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr">*** Environment<br><br>- GNU Emacs 26.1 (build 2, x86_64-p= c-linux-gnu, GTK+ Version 3.24.5) of<br>=C2=A0 2019-09-23, modified by Debi= an<br>- The code looks identical on the relevant parts in Emacs git master<= br><br>*** Steps to reproduce<br><br>1.
