Thanks. Please show the results of the following commands: (gdb) source /path/to/emacs/src/.gdbinit (gdb) frame 11 (gdb) p args[0] (gdb) xtype If the last command says "Lisp_Symbol", type "xsymbol" and tell what it prints. There are more calls to Ffuncall, in frames 14, 17, 20, 23, 27, 30, 33, and 36; please repeat the above commands, starting with the "frame NUM" command, and show the functions called by each stack frame. Next, type the following: (gdb) frame 40 (gdb) p fn (gdb) xtype Once again, if this says "Lisp_Symbol", use "xsymbol" to show the function that is being called there. Finally, type the following: (gdb) frame 110 (gdb) p error_symbol (gdb) xsymbol (gdb) p data (gdb) xtype Please note: the numbers of the frames in the above commands were taken from the backtrace you posted here: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=24417#17 Before typing these commands, please verify that the frames I mentioned are identical to those in that report. For example, frame 11 should look like this: #11 0x00000000005ee505 in Ffuncall (nargs=4, args=0x7ffe25a519b8) at eval.c:2704 internal_argbuf = {49541348, 12554, 44448, 0, 44448, 140729529997648, 5550693, 3977139728650} fun = 9484317 original_fun = 529104 funcar = 6110010 numargs = 3 lisp_numargs = 13057072 val = 47136 internal_args = 0x7ffe25a51910 count = 200 If the frames are not identical, the commands might not work, and you should try to adjust the frame numbers to what you see in the backtrace before typing the commands. Thanks.
