Then you will have to do it manually. For each stack frame N that
shows a call to Ffuncall, like this:
#7 0x00005555557be66d in Ffuncall (nargs=4, args=0x7fffffffd440) at eval.c:3068
please do:
(gdb) frame N
(gdb) print args[0]
(gdb) xtype
The last command will usually say "Lisp_Symbol", in which case follow
it with
(gdb) xsymbol
Also, try this:
(gdb) frame 17
(gdb) p data
(gdb) xtype
The last command will probably say "Lisp_Cons", in which case please
show its cells using the xcar and xcdr commands.
In general, what I see is that some command signaled an error, and the
error data includes some invalid Lisp object. The challenge is to
find that command and understand what kind of invalid object it
generates.
