Bad news: I cannot trigger this crash even in Emacs compiled with
both -DENABLE_CHECKING and -DXASSERTS=1.  Even -fno-crossjumping
was thrown in for a good measure, and didn't help (not surprisingly).

Maybe this is somehow related to libotf or something.

Let's see what you find with the GDB commands I sent earlier.
