I cannot build stable neither unstable version of findlib. The only specific thing I use LTO optimization from gentoo overlay: Using built-in specs.

Can you uplod the full build.log please?
Created attachment 745122 [details] build.log I deleted some repeated lines to prevent upload limit size.
(In reply to Ladislav Jech from comment #3) > Created attachment 745122 [details] > build.log > > I deleted some repeated lines to prevent upload limit size. Can you attach the full one compressed please? Anyway, this does indeed look totally broken with LTO. Please try -fno-lto with it. You may need to recompile dev-ml/* and dev-lang/ocaml with it too.
(In reply to Ladislav Jech from comment #5) > I cannot build stable neither unstable version of findlib. > You seem to have posted the same comment again
Yeah, sorry, my bad. Its shame I cannot delete message/edit. I will try without lto, in meanwhile I opened the bug at: https://github.com/InBetweenNames/gentooLTO/issues/792 and upstream: https://github.com/ocaml/ocamlfind/issues/24

Please not dev-lang/ocaml is already in ipa-pta.conf
The issue in the bug I linked (which seems identical to yours) is caused by strict aliasing (which is enabled at -O3). You can try -fno-strict-aliasing to see if it helps. I think LTO may just exacerbate it.
CFLAGS='-Wno-error=format-overflow -falign-functions=32 -march=broadwell -fdevirtualize-at-ltrans -fno-semantic-interposition -fuse-linker-plugin -fno-strict-aliasing -pipe -Wl,-O1 -Wl,--as-needed' still failing.
maybe do I need to rebuild also dev-lang/ocaml?
(In reply to Ladislav Jech from comment #15) > maybe do I need to rebuild also dev-lang/ocaml? Yeah, try that please, and share the log from findlib if it fails again?
Ok, it builds just fine after ocaml recompile and with these flags: * FEATURES='assume-digests binpkg-docompress binpkg-dostrip binpkg-logs config-protect-if-modified distlocks ebuild-locks fixlafiles ipc-sandbox merge-sync multilib-strict network-sandbox news parallel-fetch pid-sandbox preserve-libs protect-owned qa-unresolved-soname-deps sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync xattr' * CFLAGS='-Wno-error=format-overflow -falign-functions=32 -march=broadwell -fdevirtualize-at-ltrans -fno-semantic-interposition -fno-strict-aliasing -pipe -Wl,-O1 -Wl,--as-neede
Its bit different now, I can build again with all optimizations enabled: FEATURES='assume-digests binpkg-docompress binpkg-dostrip binpkg-logs config-protect-if-modified distlocks ebuild-locks fixlafiles ipc-sandbox merge-sync multilib-strict network-sandbox news parallel-fetch pid-sandbox preserve-libs protect-owned qa-unresolved-soname-deps sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync xattr' * CFLAGS='-Wno-error=format-overflow -falign-functions=32 -march=broadwell -O3 -fgraphite-identity -floop-nest-optimize -fdevirtualize-at-ltrans -fipa-pta -fno-semantic-interposition -flto=16 -fuse-linker-plugin -pipe -Wl,-O1 -Wl,--as-needed but I had to lower down dev-lang/ocaml optmizations: lto.conf:dev-lang/ocaml *FLAGS-=-flto* *FLAGS-=-O3* *FLAGS-=-fuse-linker-plugin* ipa-pta.conf:dev-lang/ocaml *FLAGS-="${IPAPTA}" # ICE during IPA pass: pta in lto1: Segmentation fault graphite.conf:dev-lang/ocaml *FLAGS-="${GRAPHITE}"
thank you for assitance, not sure if we should or not close it, both ocaml and findlibs are now emerged with following cflags: dev-lang/ocaml * /etc/portage/package.cflags/lto.conf -> dev-lang/ocaml: *FLAGS-=-flto* *FLAGS-=-O3* *FLAGS-=-fuse-linker-plugin* * /etc/portage/package.cflags/ipa-pta.conf -> dev-lang/ocaml: *FLAGS-="${IPAPTA}" # ICE during IPA pass: pta in lto1: Segmentation fault * /etc/portage/package.cflags/graphite.conf -> dev-lang/ocaml: *FLAGS-="${GRAPHITE}" * FEATURES='assume-digests binpkg-docompress binpkg-dostrip binpkg-logs config-protect-if-modified distlocks ebuild-locks fixlafiles ipc-sandbox merge-sync multilib-strict network-sandbox news parallel-fetch pid-sandbox preserve-libs protect-owned qa-unresolved-soname-deps sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync xattr' * CFLAGS='-Wno-error=format-overflow -falign-functions=32 -march=broadwell -fdevirtualize-at-ltrans -fno-semantic-interposition -pipe -Wl,-O1 -Wl,--as-needed' dev-ml/findlib * FEATURES='assume-digests binpkg-docompress binpkg-dostrip binpkg-logs config-protect-if-modified distlocks ebuild-locks fixlafiles ipc-sandbox merge-sync multilib-strict network-sandbox news parallel-fetch pid-sandbox preserve-libs protect-owned qa-unresolved-soname-deps sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync xattr' * CFLAGS='-Wno-error=format-overflow -falign-functions=32 -march=broadwell -O3 -fgraphite-identity -floop-nest-optimize -fdevirtualize-at-ltrans -fipa-pta -fno-semantic-interposition -flto=16 -fuse-linker-plugin -pipe -Wl,-O1 -Wl,--as-needed' do you think I should report it upstream?
I think it's already fixed upstream (see the bug I linked) but only in newer OCamls. I've added filtering to the ebuild too and I think it should be OK now.
