Please describe the problem.

After updating my Synology DS216+ NAS from 6.2-23739-1 to 6.2-23739-2, running git-annex with any non-trivial command, locally on the NAS or remotely on the NAS results in:

git-annex: timer_create: Bad address

I'm guessing that this means that a library function the standalone binary needs is no longer present, but I'm unsure why. The -1 to -2 update seems to only have two security fixes (SA 18-36, and SA 18-01 -- the latter being a Spectre/Meltdown bug).

Do you know if timer_create is a kernel system call? Or a libc (etc) library function?

What steps will reproduce the problem?

Update Synology NAS to 6.2-23739-2, run git annex sync, git annex version or similar (remotely or locally).

What version of git-annex are you using? On what operating system?

x86-32, stand alone build, for ancient-kernels, as that the 64-bit stand alone build no longer seemed to work due to locale issues (see note added at the end).

I believe it is 6.20180626, but git annex version currently also fails...

Please provide any additional information below.

ewen@nas01:/volume1/music/podcasts$ hostname --fqdn
ewen@nas01:/volume1/music/podcasts$ git annex sync
git-annex: timer_create: Bad address
ewen@nas01:/volume1/music/podcasts$ git annex version
git-annex: timer_create: Bad address
ewen@nas01:/volume1/music/podcasts$ uname -mr
3.10.105 x86_64

There is a 6.2.1 firmware release for the Synology NAS released a couple of days ago, but it does not yet seem to be visible to my NAS. I can try that one if it'd help.

I can also try switching back to one of the more modern x86-64 / x86-32 stand alone builds if that'd help. But then I'd need some assistance with working around the:

sh: loadlocale.c:129: _nl_intern_locale_data: Assertion `cnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))' failed.
error: git-annex died of signal 6

error I was seeing on those builds. (From other work elsewhere it feels a lot like the LC_TIME structure changed in size in some libc definition somewhere in the last 6-12 months; in another project we had a similar break on Ubuntu 18.04 issues which didn't affect Ubuntu 16.04 and earlier.)

In case it helps, out of the box defaults give:

ewen@nas01:/volume1/music/podcasts$ echo $LANG
ewen@nas01:/volume1/music/podcasts$ ls /volume1/thirdparty/git-annex.linux/locales/en_US.utf8/

(although those files are currently generated with the now broken x86-32 legacy standalone build).

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Definitely. It was working until I updated the NAS firmware image this afternoon... for this repository holding years of podcasts and many others.
