On 24.3, you get a weirdly disfunctional (and very entertaining)
Emacs, but it doesn't crash.

Why do you start bootstrap-emacs?

In any case, I cannot reproduce this with the latest trunk.  It could
be the bug I introduced in 115796 and fixed in 115797.

Because that was the only way I got any reaction in the first place.
And that's what gdb proposes here.
