pdumper bootstrap error

[Alan Third]

I think I must be doing something wrong, because I’m randomly getting
errors like this:

  GEN      loaddefs.el

9085c29485c3842b30a84ab3d55121be1b04f8aea81a5273ff244956164833a5
found fingerprint:

emacs: could not load dump file "../src/bootstrap-emacs.pdmp": not built for 
this Emacs executable
make[2]: *** [loaddefs.el] Error 1
make[1]: *** [../lisp/loaddefs.el] Error 2
make: *** [src] Error 2

I’m not doing anything unusual that I’m aware of. I ran make, then ran
emacs, then ran make again, having made no changes, and got this
error. The only way past it I can see is to do a make bootstrap, which
slows down development quite a lot.

I’ve attached the terminal output for the last couple of runs of make.
