Edit report at https://bugs.php.net/bug.php?id=80371&edit=1 ID: 80371 Updated by: nikic@php.net Reported by: paternostersergio6 at gmail dot com Summary: Sigfault on function call Status: Open Type: Bug Package: Scripting Engine problem Operating System: Ubuntu 16.04 Server PHP Version: 8.0.0RC4 Block user comment: N Private report: N New Comment: Would it be possible to run your code under "USE_ZEND_ALLOC=0 valgrind php" and post the resulting log (on gist.github.com for example, it will likely be large)? Previous Comments: ------------------------------------------------------------------------ [2020-11-15 16:35:53] paternostersergio6 at gmail dot com Description: ------------ I do apologize but this bug is too hard to reproduce outside of a complex framework I'm using. I hope the *backtrace* below could help. The segmentation fault happens when I call a static method in a class that just returns true. My (minimal) configuration. No particular changes in php.ini. sudo ./configure --prefix=/usr/local/php/8.0.0RC4 \ --with-pdo-mysql=mysqlnd \ --enable-debug Test script: --------------- /* Note this script works well! It is just to give you an idea of what happens in my framework */ class Process{ public static function isSpecial(string $customernumber) :bool{ // does some checks return true; } public static function addChannel( array $a) :array{ // THIS GENERATES THE SIGFAULT if( self::isSpecial($a['Customer Number']) ) $a['Channel'] = 'AB2'; else $a['Channel'] = 'AB1'; return $a; } } $a = []; $a['Customer Number'] = 'A100200'; $a = Process::addChannel($a); Actual result: -------------- GNU gdb (Ubuntu 7.11.1-0ubuntu1~16.5) 7.11.1 This GDB was configured as "x86_64-linux-gnu".
