Previous Comments: ------------------------------------------------------------------------ [2016-04-04 21:13:36] kalle@php.net Is there an actual error that can occur this early on in the startup stage? If so, do you have a script to reproduce such? ------------------------------------------------------------------------ [2015-02-07 05:52:22] reeze@php.net Description: ------------ https://github.com/php/php-src/blob/PHP-5.4/main/main.c#L2037-L2051 EG()/PG() are initialized after zend_startup(). zend_error() assumed EG() are initialized correctly, when build with ZTS, EG() are not correct initialized, this will crash PHP if there is a branch called zend_error() function. This seems exist since PHP4.0 Test script: --------------- None: You could try to adding a zend_error() call to this line: https://github.com/php/php-src/blob/PHP-5.4/main/main.c#L2039 Expected result: ---------------- No crash Actual result: -------------- * thread #1: tid = 0x1dc8e, 0x000000010020109e php`php_error_cb(type=2, error_filename=0x000000010042ae0c, error_lineno=0, format=0x0000000100446dd7, args=0x00007fff5fbff370) + 94 at main.c:952, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x48) frame #0: 0x000000010020109e php`php_error_cb(type=2, error_filename=0x000000010042ae0c, error_lineno=0, format=0x0000000100446dd7, args=0x00007fff5fbff370) + 94 at main.c:952 949 int buffer_len, display; 950 TSRMLS_FETCH(); 951 -> 952 buffer_len = vspprintf(&buffer, PG(log_errors_max_len), format, args); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69001&edit=1
