--- Comment #5 from David Barto <barto at cambridgesemantics dot com> ---
The code uses so many un-aligned access operations (legal in x86 code) that
using -fsanitize=undefined causes the code to stop execution very early in the
startup.

If, after fixing this, the problem still exists, I'll be back to re-open the
bug.
