Some observations:

Calls a tramp handler?

We are inside a timer handler here:

That timer handler (at some point) calls accept-process-output, which
calls wait_reading_process_input, which may run timers (and does so).

We are inside a timer handler here:

I suppose this calls a tramp handler.

Tramp handler calls accept-process-output, which calls
wait_reading_process_input, which may run timers (and does so).

I suppose this calls a tramp handler.

I suppose you did C-x C-f ?



So we in three levels of tramp handlers and two levels of
accept-process-output, wait_reading_process_input, and timer_check.

I just installed a change to make wait_reading_process_input reentrant
which may or may not be relevant to this crash.
