Hello,

editors/emacs-devel was marked broken on aarch64, due to the sbrk issue (they are still using sbrk, which is not available on aarch64). When manually removing the BROKEN directive, it seems to build, however the bootstrap-emacs segfaults:

I've tried the latest git checkout as well (example is from that), it fails with it as well.

So, maybe not sbrk is the issue anymore, and it should build.

Best regards,
