Follow-up Comment #7, bug #60077 (project make):
I wonder if &: makes sense as a pattern rule since regular pattern rules
already support multiple targets.
Regardless, I have also tested your implicit test without the & and get the
same results:
$ cat ../makefile4
.SECONDEXPANSION:
all: world
It gives the same error:
src/main.c:1954:16: error: writes 1 byte in a region of size 0
[-Werror=stringop-overflow=]
1954 | *(p - 1) = '\0';
| ~^~

Is this just a style warning being turned into an error?
That is, would this compile if the line was rewritten as:
*(p - 1) = ‘\0’;
Which means the same thing per the spec?
If the rewrite would fix it, I suggest doing the rewrite, to
reduce compilation problems.
