Yea, I'm hitting this more and more often. Especially with the new eBPF backed profiling tools like bcc, which, for the forseeable future, only support frame pointer based unwinding. Also fp based unwinding is a lot more efficient. > What would it take for such an alternative to exist (can the Debian > alternatives system work for libc)? I was thinking of adding a libc6-frame-pointers which would replace (and conflict with) libc6. But that's just because it was what I could think of. Maybe it'd be better to let those be co-installed by using a different triplet and allow to chose which to use via /etc/ld.so.conf/something? Not pretty either :( > If other people want this, I'm interested in investing some time into > helping with it. Same here. I'd primarily like some guidance about what approach is more likely to be accepted. Greetings, Andres Freund
