Emacs Crashes as soon as I load Tramp - to replicate:

emacs -Q
M-: (require 'tramp)

After requiring tramp emacs freezes. Running top shows that emacs is
grabbing ram as fast as it can untill I kill it.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file

What happens, if you don't require Tramp, but open a remote file (or
directory) instead of? Something like

emacs -Q
C-x C-f /ssh::

Furthermore, could you, please, apply (setq debug-on-signal t) before
running the test. Immediately after Tramp hangs, try to kill it with
C-g and show the backtrace.

Best regards, Michael.

Hey Michael - Thanks for taking a look at this.

Attempting to load a networked file also crashes emacs.

Unfortunately setting debug-on-signal or debug-on-quit doesn't produce a
backtrace - emacs won't respond to C-g and I have to kill the emacs process.
Tonight 'll attempt to run the emacs process under gdb, and grab a stack
trace that way.

Sometimes, it helps to send the frozen Emacs process the FPE signal.

Best regards, Michael.

bug#7402: 23.2; loading tramp causes emacs to freeze

[Hans Rosenfeld]

I have the same problem with a 32bit emacs on a 64bit Solaris x86. As
soon as I try to open a remote file, emacs freezes and can only be
killed with SIGKILL. This does not happen when running emacs as root.

Hmm. Sometimes, it is possible to reanimate a frozen Emacs sending
SIGFPE from a shell. Could you try this? If you set debug-on-error to t
before loading Tramp, we would get an elisp backtrace, which might tell
us more.

Best regards, Michael.

With debug-on-error set, it hangs after "entering debugger" in the
minibuffer. SIGFPE doesn't work, but I get this from pstack:

I rebuilt emacs without dbus support, and it did not show the original
problem, tramp just works.

This reminds me of bug#6579, which was reported later also for
Cygwin. Shall be fixed meanwhile in the emacs-23 branch.

Do you have a chance to test Emacs 23.2.92, available at
<ftp://alpha.gnu.org/gnu/emacs/pretest/emacs-23.2.92.tar.gz>?

Best regards, Michael.

This is 2 years ago. Do you still suffer from that problem, with a more
recent Emacs version?

I can't reproduce it anymore with Emacs 24.2.
