Emacs 25.3 alpine arm64 lisp/term/ns-win.elc memory leak?

Hello,

When building Emacs 25.2 & 25.3 on arm64 one file takes 100% CPU and more
and more memory until it gets killed by the OOM killer:

Alpine needs the following patches for Emacs to build:

-
https://git.alpinelinux.org/aports/plain/community/emacs/gamedir.patch?h=3.7-stable
-
https://git.alpinelinux.org/aports/plain/community/emacs/musl.patch?h=3.7-stable
-
https://git.alpinelinux.org/aports/plain/community/emacs/noaslr-dump.patch?h=3.7-stable

If anyone has a clue about what I could try that'd be very welcome.

The patches are not needed anymore in Emacs 26.1, which compiles without
any problem on alpine.

Kind regards,
Philippe

Is it only dying on `ns-win.elc`?  If so, you can try to just remove
`ns-win.el`, since that's only useful under macOS.

Thanks. Just deleting it makes the build fail, but editing it and
deleting most of it seems to work, then something else fails. I'll try
to continue that path and see how it goes.

For the record I found out that `make -j $(nproc)` triggers the error
while `make` doesn't. I need to confirm that in the CI but this issue
seems fixed.

Probably that Emacs < 26.1 was not really "parallel ready", at least on alpine.

I confirm `make` fixes it:
