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.
