Hoping to see an > updated dwarves in rawhide soon ;) Thanks a lot! I've updated a f33 system to rawhide to test all this, fixed up some extra warnings wrt mallinfo(), strndup() error path handling/potential buffer overflow issue and will add a conditional define for DW_FORM_implicit_const found in the libbpf CI tests that Andrii pointed out to me, then go and tag 1.20 and do the rawhide/fedora package update dance. - Arnaldo > [1] https://github.com/acmel/dwarves/ > [2] https://copr.fedorainfracloud.org/coprs/omos/kernel-btf-test/build/1930103/ > [3] https://copr.fedorainfracloud.org/coprs/omos/kernel-btf-test/build/1930104/
