This second backtrace you posted doesn't seem to be the same as what you
had before.  It would help to figure out what Lisp code is being run.

Could you run Emacs in gdb, preferably with an unoptimized build, and
try getting another backtrace?  Please start from the Emacs src/
directory, so that you get a Lisp backtrace in gdb instead of just a C
backtrace.

Thanks.
