I'm getting this on one of my machines:

/bin/bash: line 1: 2759815 Bus error               EMACSLOADPATH= '../src/emacs' -batch --no-site-file --no-site-lisp --eval '(setq load-prefer-newer t)' -f batch-byte-compile cedet/semantic/bovine/c-by.el
make[3]: *** [Makefile:295: cedet/semantic/bovine/c-by.elc] Error 135
make[3]: *** Waiting for unfinished jobs....
make[2]: *** [Makefile:318: compile-main] Error 2
make[1]: *** [Makefile:411: lisp] Error 2
make: *** [Makefile:1126: bootstrap] Error 2

It's reproducible in that I always get this when I say "make", but if I
instead say

./src/emacs -batch --no-site-file --no-site-lisp --eval '(setq load-prefer-newer t)' -f batch-byte-compile cedet/semantic/bovine/c-by.el

everything works as it should, and it makes the .elc file.

So I'm not sure how to debug this...

On my laptop (which is also Debian bullseye), I'm not seeing any problems.

I fixed that, installed, and am marking the bug as done. Thanks very much.
