Some quick searching on google, it looks like the cleanest fix for that bug is dahdi-tools needs to be patched to only include execinfo.h or only use backtrace() on glibc-based systems, and that patch then sent to the dahdi-tools upstream developers for inclusion in a future release. That way, we're not dragging that patch around forever in the tree or in the musl overlay. It also doesn't look like musl itself will ever implement execinfo.h or backtrace(), per this message in 2015 from the lead musl developer: https://www.openwall.com/lists/musl/2015/04/09/3 -- Joshua Kinard Gentoo/MIPS [email protected] rsa6144/5C63F4E3F5C6C943 2015-04-27 177C 1972 1FB8 F254 BAD0 3E72 5C63 F4E3 F5C6 C943 "The past tempts us, the present confuses us, the future frightens us.
