28.0.50; Emacs doesn't start if the current directory is inaccessible |
|

1. Create a FUSE mount where the FS driver runs in the foreground,
e.g. using
bindfs -f /bin /tmp/foo
2. In another shell, cd into the new mount point:
cd /tmp/foo
3. Kill the bindfs process started in step (1) (e.g. using C-c).
4. In the shell (2), start Emacs:
$ emacs -Q
Error getting directory: Transport endpoint is not connected
Symbol’s value as variable is void: auto-save-list-file-prefix
The "void variable" error is clearly a bug. In general, Emacs should
fall back to / or ~ if the current directory is inaccessible.
The Lisp backtrace is
"default-toplevel-value" (0xffffb650)
"custom-initialize-reset" (0xffffbc00)
"custom-declare-variable" (0xffffc270)
"byte-code" (0xffffc740)
"display-warning" (0xffffcf30)
"normal-top-level" (0xffffd600)
i.e. it looks like `display-warning' is called too early.
