09:26:51 <jfqd1> jperkin: With the latest php 8.2 update in trunk we get "Memory fault(coredump)" crashes when running php on the commandline. Nextcloud for sample has a cron script, which now fails sometimes but not every time. Strange is, that there is no coredump. Any idea what changed in the latest php 8.2 update?
09:27:52 <jperkin> no, can you get a reproducer for me? core dumps will be wherever coreadm has them configured
09:41:13 <jfqd1> jperkin: Sorry, what do you meen be reproducer? For Nextcloud the cron script is like:  /opt/local/bin/php /var/www/htdocs/nextcloud/current/cron.php
09:41:26 <jperkin> a way to reproduce the crash
09:41:38 <jfqd1> We are using the regular coreadm config, no changes.
09:41:48 <jperkin> I don't have any php cores on my build hosts, so it's not something that is triggered by any of the php package builds at least
09:42:28 <jperkin> so it says coredump but there's no core in the coreadm directory?
09:45:09 <jfqd1> jperkin: reproducing will be difficult, cause it not always crashes only sometimes. I will first create a new image with php 8.3 and will see if the issue goes away. Yes it says coredump, but no core file in /var/cores
09:47:03 <jperkin> /var/cores isn't the default?
09:47:05 <jfqd1> Ah I see there are core files in /zones/<uuid>/cores. OK, will investigate and come back :-)
09:47:27 <jperkin> ah, good, so pstack on one of them will at least give some basic clues as to what to look for
09:50:20 <jfqd1> jperkin: Crashes in  fffffc7feefe895d iconv (1889b50, fffffc7fffdfda78, fffffc7fffdfda80, fffffc7fffdfda90, fffffc7fffdfda88) + 2d
09:50:41 <jfqd1> So it might be more an issue of iconv?
09:51:17 <jperkin> can you gist the full stack somewhere? as a workaround you may find LANG=C or whatever helps
09:52:18 <jperkin> the only thing I can think of that might be related is the recent icu update
09:55:11 <jfqd1> jperkin: gist is here: https://gist.github.com/jfqd/43a2994f5f36e68896a501eda83bb66f
09:55:34 <jfqd1> And I added LANG=C and will see what is happening :-)
09:55:55 <jfqd1> Thx a lot for your help!
09:56:14 <jperkin> I'll dig around the icu/iconv/php-iconv test suites and see if they trigger anything
10:21:28 <jperkin> ok, good news is that php-iconv tests also fail and dump core, so I have plenty to go on ;)
10:30:10 <jperkin> ok found the problem, I'll get that in the next build
16:42:16 <jfqd1> jperkin: Thx for digging into it! Be happy to test if the next trunk updates are ready :-)
16:50:32 <jperkin> I've merged it early so will let you know when available
