I'm not sure how this can be even related to this bug, however can you elaborate? "tends to break" is not really clear to me what it means. On my system I have no issues that can be correlated to -fpic, afaik. I admit I'm not really sure how pie can interfere with PIC for share libraries, to be honest. Do you have some links to collect more info? THanks. (In reply to Guillaume Ceccarelli from comment #11) > I can confirm that this bug occurs on -flto=N for N > 1.

On my system the compilation that failed before goes thru by using -flto=1 Thanks. This fails:
CFLAGS="-O2 -flto=4 -pipe"
CXXFLAGS="${CFLAGS}"
LDFLAGS="${CFLAGS}
This works:
CFLAGS="-O2 -flto -pipe"
CXXFLAGS="${CFLAGS}"
LDFLAGS="${CFLAGS}
I think this preliminary points us as at LTO partitioning bug in gcc, not the problem in dev-libs/isl package.
Got very fancy reproducer locally. Will post more detail tomorrow. The investigation so far: The gist of a bug is 'all.c' file in new isl-0.21 release. It tricks libtool (or gcc?) into sourcing all.o as an input to intermediate lto partitions and breaks things. One of the workarounds is to rename all.c source file into something else in irc release. I'll spend some time tracking down special all.o handling tomorrow. Here is the full reproducer:
$ cat foo.bash
#!/bin/bash
export LANG=C
cc=gcc
mk() {
local flag=$1
rm -rf -- *.o *.so*
${cc} ${flag} -fPIC -c all.c -o all.o
${cc} ${flag} -fPIC -c isl.c -o isl.o
# Note: all.o is not used here and yet in interferes with -flto=4
${cc} ${flag} -fPIC -shared isl.o -o libisl.so
}
# empty files are enough to trigger a bug
touch all.c isl.c
echo "=== -flto=1 (works) ==="

0001-isl-rename-all.-c-h-to-all_headers.-c-h.patch
0001-isl-rename-all.-c-h-to-all_headers.-c-h.patch is a working workaround for isl ebuild until gcc is fixed.
The bug has been referenced in the following commit(s): https://gitweb.gentoo.org/proj/gcc-patches.git/commit/?id=6480d86a84ad176452fa3b269570f372bcf84d6e commit 6480d86a84ad176452fa3b269570f372bcf84d6e Author: Sergei Trofimovich <slyfox@gentoo.org> AuthorDate: 2019-04-04 06:57:36 +0000 Commit: Sergei Trofimovich <slyfox@gentoo.org> CommitDate: 2019-04-04 06:57:36 +0000 8.3.0: backport -flto=2 build failure on isl (all.c) Reported-by: Fabio Coatti Bug: https://gcc.gnu.org/PR89896 Bug: https://bugs.gentoo.org/682018 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org> 8.3.0/gentoo/27_all_flto-make-all.patch | 31 +++++++++++++++++++++++++++++++ 8.3.0/gentoo/README.history | 1 + 2 files changed, 32 insertions(+) Queued gcc fix for next gcc-8.3.0 patchset.
