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
