If so, are there any compiler warnings? [1] <https://www.php.net/supported-versions.php> ------------------------------------------------------------------------ [2018-04-24 16:47:19] inari at sosteam dot jp I'm sorry there is a　mistake in test script, here is the correct　script: <?php function test(){ $TEST['A']['A'] = 1; $TEST['A']['B'] = implode("test", $TEST['A']['B']); } test(); ?> ------------------------------------------------------------------------ [2018-04-24 16:28:15] inari at sosteam dot jp Thank you for reply. here is the cpu model: Intel Xeon W-2145 Thank you! ------------------------------------------------------------------------ [2018-04-24 16:24:19] levim@php.net What CPU model do you have? ------------------------------------------------------------------------ [2018-04-24 16:08:12] inari at sosteam dot jp Description: ------------ test in php-fpm+nginx and php+apache,if any wrong part in php code(but it can run on the php with gcc compiler normal),and php will crash, nginx and apache will return error 500. I collect some crashes information,seems it was all with opcache. And then I disabled opcache,now it could run php code normal. Here is the build informations - Compiler: Intel C Compiler 2018 update 2(18.0.2.199 Build 20180210) PHP Version: 7.3.0-dev(jit-dynasm) Build options: --enable-debug --disable-cgi --enable-cli --enable-fpm --enable-opcache CFLAGS="-O0" CXXFLAGS="-O0" without any changes in php.ini I put one of crash example code at test script. How could fix it without crash? Sorry for my bad english, thank you for helping! Test script: --------------- <?php function test(){ $TEST['A']['A'] = 1; $TEST['A']['B'] = implode("test", $TEST['A']['B']); } test() ?> Expected result: ---------------- It's could run without error like build with gcc.
