Previous Comments: ------------------------------------------------------------------------ [2018-08-07 14:38:25] cmb@php.net Thanks, Sebastian! I did run valgrind on a build (master@8c76dc3) where the test succeeds, and get a long list of errors[1]. My configure line: ./configure --disable-all --disable-cgi --disable-phpdbg --enable-phar --enable-json --enable-filter --with-iconv --with-openssl --enable-hash --enable-libxml --enable-dom
