Well mine are different to the ones I reported in February which always
included:

  ...
  #4  0x080e89d1 in x_catch_errors_unwind (dummy=137858041) at xterm.c:7543
  #5  0x0818dc6e in unbind_to (count=44, value=137858041) at eval.c:3233

I attach the bottom part of the backtraces for the garbage collection related
