Description
mariadb fails on startup with latest glibc 2.32/2.33
The exact same version (10.5.8) ran fine on older GLIBC, prior to all packages rebuilt for latest glibc 2.33 and 2.32, everything worked fine on glibc 2.30 prior to that.
Do you use lchmod? This is identical problem with rsync where Wayne D, says lchmod is used in latest glibc and may be cause.

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Server version: 10.5.8-MariaDB-log
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=0
max_threads=153
thread_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 466473 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Not that I can see, but I might be reading it all wrong,
I have attached 2 files
GGGGGGGG is strace std output
FFFFFFFFFF is strace with -f output
An extract from FFFFFF (-f is needed to capture the mysqld process rather than the mysqld_safe script).

So file descriptor 9 is the ibdata1 file. As you are running the same code as before you upgraded glibc the SIGILL isn't part of mariadb otherwise it would of failed earlier. Note the futex call here never returns. Its quite possible that the futex call in the kernel or glibc has the SIGILL.
Given the duplicate bug references here is also a x86 reference on slackware I'd be looking closely at their build process and bug reports for something similar.
OK, i'll pass it back to them, they didnt seem interested before sigh will see what happens now
Thanks Daniel
https://sourceware.org/glibc/wiki/Testing/ABI_checker maybe. I'm not sure this calls the APIs but maybe the interface checks is sufficient.
Otherwise
nobby6 thanks for your interest in further testing. Development/testing versions produced by our CI are available here http://hasky.askmonty.org/archive/10.5/.
Apologizes for preemptively closing this issue.
No problem,s thanks, happy to confirm mariadb started correctly, and has been running now since 30 hours on 32bit dev box.
There's no lchmod used in mariadb server.
Are you able to ulimit -c unlimited and get a backtrace from where this occurred?
Or an strace to see if the `std::unique_lock<std::mutex>::unlock` calls resulted in a futex syscall before termination.
