Sounds like a bug, because I now get

  Lisp Backtrace:
  0x90310000 Lisp type 0
  0xb2890000 Lisp type 0
  0xaf790000 Lisp type 0
  0x17190000 Lisp type 0
  0x6dd10000 Lisp type 0
  0x6f110000 Lisp type 0
  0x15890360 Lisp type 4
  0x81910000 Lisp type 0

where I should have seen a real Lisp backtrace, judging by the C
backtrace:
