Dear Maintainer, While trying to update php-league-csv from 9.20.1 to 9.22 I faced an issue on trixie runnning PHP 8.4.4 The build job, that invokes phpunit for the tests fails this way. https://salsa.debian.org/php-team/pear/php-league-csv/-/jobs/7206384 Running the same tests with phpunit through composer leads to the same issue. Running the same tests with phpunit through composer but on bookworm, that runs 8.2, doesn't fail. Upstream runs the tests in a github actions job on PHP 8.4.4 without issue either. So issue doesn't seem to be related to phpunit, and maybe it is related to the php version shipped in debian. Output: ------------------------- phpunit --exclude-group network --no-coverage PHPUnit 11.5.8 by Sebastian Bergmann and contributors.

I found that if I invoke phpunit with `XDEBUG_MODE=coverage` there is no failure.
I found that if I uninstall php8.4-xdebug there is no failure.

Thanks for your reply. But is this xdebug issue or php issue? Le vendredi 7 mars 2025, 08:11:35 CET Ondřej Surý a écrit :
Xdebug issue. Well, at least I would start reporting this to xdebug and Derick will handle this if this is PHP issue anyway. -- Ondřej Surý (He/Him)
This would be best reported to xdebug upstream. This is the latest upstream version, so this needs to be fixed upstream. Ondrej -- Ondřej Surý (He/Him) ondrej@sury.org

Hello, The bug has been fixed upstream in 3.4.6 , could you please update the version in Debian? Latest is 3.4.7 at the moment Regards Fab
Hi, Please update xdebug in Debian. This bug has fixed upstream for a few months and was causing FTBFS in php-league-csv which has a workaround because of it and is apparently causing other issues now. Regards Fab
Dear Ondrej, Apparently the new issue in php-league-csv is now caused by php 8.4.16 See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1124191 https://github.com/thephpleague/csv/issues/572 Nevertheless, update of xdebug would be still very useful and permit to remove a workaround specific to debian in php-league-csv Regards
