Emacs version aside, this appears almost identical to the other bug of same name: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=38648 Using tramp, I had a remote cpp file open in a window. I pressed "C-c c", which invokes a function in my .emacs called compile-hereish, which (in this case) invokes the compile command with the remote directory containing the remote cpp. Compilation runs as expected, throwing certain cpp syntax errors. Now, if I click on the red error text in the *compilation* window, I get a prompt like: Find this error in (default ): /ssh:@:/System/Volumes/Data/ If I press enter, to confirm, I get a [No match] error I believe this may be a newly revealed issue under macos Catalina. Of possible note (especially the last), these are the mounts on local (macos) machine: $ sudo mount /dev/disk1s5 on / (apfs, local, read-only, journaled) devfs on /dev (devfs, local, nobrowse) /dev/disk1s1 on /System/Volumes/Data (apfs, local, journaled, nobrowse) /dev/disk1s4 on /private/var/vm (apfs, local, journaled, nobrowse) map auto_home on /System/Volumes/Data/home (autofs, automounted, nobrowse) Might the fix in 27.1 referenced in report #38648 need to be back-ported to 26.x? As per autogenerated report below, I am using emacs 26.2 installed via brew on macos.
