Follow-up Comment #1:

I don't see how the "second" xrealloc() would return 0; the entire point of
xrealloc is that it never returns 0.

However, I can see where the behavior of the code might lead to an infinite
loop.

This issue was already addressed in GNU Make 4.3 via bug #13651
The version you're testing (4.2) was released in 2016.

It's certainly helpful to check for errors in tools like GNU Make but please
check either the most recent published version or, even better, the current
Git HEAD version.

Thanks!
