OpenWrt 19.07 uses musl 1.1.24 OpenWrt 18.06 uses musl 1.1.19 I also checked that this is really using this version and not just claims to do so. I assume that some vendor forked a random OpenWrt master state and had a problem with their broken application and "fixed" it by downgrading musl, but they only changed the git commit hash which should be used and not the version number. I saw that lynxis just send this patch to use the official tar.gz for musl and not check musl out from git any more, I assume this is related to this discussion: https://email@example.com/ Hauke Download attachment "signature.asc" of type "application/pgp-signature" (489 bytes)
