reproduced same kind of issue in emacs 25 using slightly more
complicated lisp code, plenty of ram left:
first file seqfile1:
(setq undo-outer-limit (expt 2 23))
(setq max-lisp-eval-depth (expt 2 17))
(setq max-specpdl-size (expt 2 17))
(setq message-log-max 40000)
(setq shell-command-default-error-buffer 'stderror-buffe)
(setq max-lisp-eval-depth (expt 2 16))
(defun insert (L)
(message "insert into urls values ('%s',%i);" L counter)
(setq counter (+ 1 counter))
)
(defun insertall (L)
(map 'insert L))
(setq counter 28531843)
(insertall
'(
seqfile2:
seq 11718 > seqfile1
seqfile3:
))
cat seqfile1 seqfile2 seqfile3 > seqfile4
run each command in seqfile4 in order, same result: emacs segfault after
#77287 frames, plent of ram left
slightly different stack trace (but that could be because it's got
different lisp code leading to it)
virtual memory at segfault; 458mb
resident memory: 75mb
