Failed to add a package if there is too much dependencies

When a package has too much dependencies (in my example >=755), apk add fails with a non explicit error message. This can be reproduced with docker like this:

• Create an APKBUILD and put it in it dedicated folder (test-f)
• Docker command docker run --rm -it -v "$(pwd):/workdir" -w /workdir alpine:3.12 /bin/sh
• Generation and triggering of the bug

apk add abuild
abuild-keygen -a -n -q
( cd test-f/ && abuild -Fr )

apk add darkhttpd
darkhttpd /root/packages &

apk info --allow-untrusted -X http://127.0.0.1/workdir/ --repositories-file /dev/null test-f
apk update --allow-untrusted -X http://127.0.0.1/workdir/ --repositories-file /dev/null test-f
apk add --allow-untrusted -X http://127.0.0.1/workdir/ --repositories-file /dev/null test-f

This is triggering this message :

/workdir/test-f # apk add --allow-untrusted -X http://127.0.0.1/workdir/ --repositories-file /dev/null test-f
