dev-libs:elfutils-0.173:20180708-192752.log

On my mostly-stable hardened amd64 machine, I have a default CFLAGS setting that includes "-fno-unwind-tables -fno-asynchronous-unwind-tables -fomit-frame-pointer" by default, and invert those flags (as well as adding -ggdb) for some packages using package.env. With those flags in CFLAGS, elfutils-0.173 fails two tests, run-deleted.sh and run-next-cfi-self.sh (0.172 also fails the former, and does not include the latter; 0.170-r1 exhibits a different and apparently-unrelated set of test failures), but when I change "-fno-asynchronous-unwind-tables" to "-fasynchronous-unwind-tables", both 0.172 and 0.173 pass their tests. Perhaps "-fno-asynchronous-unwind-tables" should be filtered out, or "-fasynchronous-unwind-tables" added (as "-g" is in src_configure)?

Comment 1 Jonathan Lovelace 2020-07-19 19:41:44 UTC
This still affects versions 0.177, 0.179, and 0.180.
Comment 2 Andreas K. Hüttel archtester gentoo-dev 2023-08-22 21:58:41 UTC
Is this still relevant?
Comment 3 Jonathan Lovelace 2023-08-22 22:27:18 UTC
Yes: with my usual CFLAGS I still see a failure of run-deleted.sh in both 0.188 and 0.189-r3, and both of those versions pass their tests once I use package.env to add my "debug" config adding "-ggdb -funwind-tables -fasynchronous-unwind-tables -fno-omit-frame-pointer" to CFLAGS.
