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
