patch
Please try the attached patch.
(In reply to Tijl Coosemans from comment #2) Thank you Tijl, this patch solved it and collectd5-5.12.0_9 runs with gettext-runtime-0.22. I'm seeing something similar with podman and buildah - upgrading to gettext-runtime-0.22 makes both start crashing: lab2# podman version zsh: segmentation fault podman version lab2# sudo pkg add -f /var/cache/pkg/gettext-runtime-0.21.1.pkg Installing gettext-runtime-0.21.1... package gettext-runtime is already installed, forced install Extracting gettext-runtime-0.21.1: 100% lab2# podman version Client: Podman Engine Version: 4.6.0-rc2 API Version: 4.6.0-rc2 Go Version: go1.20.3 Built: Mon Jul 17 10:44:05 2023 OS/Arch: freebsd/amd64 With gettext-0.21.1, when /usr/local/lib/libintl.so.8 constructors are called, _libpthread_init is called which initialises current pthread and later init_rwlock is called which needs current pthread. WIth gettext-0.22, init_rwlock is called befpre _libpthread_init and current pthread is null and things go pear shaped For buildah, podman and skopeo, the dependency on gettext is coming via security/gpgme https://lists.freebsd.org/archives/dev-commits-src-main/2023-July/017009.html from Sunday is for "git: ad056b5d35d9 - main - libthr: trigger library initialization on rwlock calls" in FreeBSD main (so: 14) Created attachment 243431 [details]
gettext-runtime patch
Please try this patch for devel/gettext-runtime. It should fix all crashes.
The gettext-runtime patch works for podman, buildah and skopeo. Thanks for the quick response! (In reply to Tijl Coosemans from comment #7) I can also confirm, that with the patched version gettext-runtime-0.22_1 the non-patched build of collectd5-5.12.0_8 does not crash any more.

This can happen because libintl doesn't link to libpthread to avoid the overhead for non-threaded programs. To fix this, add an initialisation function to libintl that triggers initialisation of libpthread. RTLD_NOLOAD suggested by kib. dlopen was fixed to work during initialisation in https://cgit.FreeBSD.org/src/commit/?id=1005d3d05362 PR: 272472, 272517 Mk/Uses/gettext-runtime.mk | 5 ++-- devel/gettext-runtime/Makefile | 2 +- .../gettext-runtime/files/patch-intl_osdep.c (new) | 28 ++++++++++++++++++++++ 3 files changed, 32 insertions(+), 3 deletions(-) |
After the update from devel/gettext-runtime 0.21.1 -> 0.22 and then (re)starting collectd it fails with this: riddler:~/ # /usr/local/etc/rc.d/collectd restart collectd not running? Starting collectd. Segmentation fault (core dumped) /usr/local/etc/rc.d/collectd: WARNING: failed to start collectd Tried to rebuild all dependencies between devel/gettext-runtime and net-mgmt/collectd5, e.g. security/libgpg-error, security/libgcrypt and net-mgmt/collectd5 itself, but this did not help. What finally helped was to downgrade to devel/gettext-runtime 0.21.1.
