Edit report at https://bugs.php.net/bug.php?id=76850&edit=1 ID: 76850 Updated by: cmb@php.net Reported by: cschneid at cschneid dot com Summary: Exit code mangled by set locale/preg_match -Status: Open +Status: Verified Type: Bug Package: PCRE related Operating System: Linux PHP Version: 7.3Git-2018-09-07 (Git) -Assigned To: +Assigned To: ab Block user comment: N Private report: N New Comment: Thanks for reporting! I can confirm the issue, and also that the regression has been introduced with commit 684ce24[1]. valgrind reports a single memory leak regarding a zend_string[2], but it also reports this leak for earlier commits. However, running with a debug build yields: [Sat Sep 8 13:26:03 2018] Script: '/mnt/c/Users/cmb/php-dev/76850.php' /mnt/c/Users/cmb/php-dev/php-src/Zend/zend_string.h(133) : Freeing 0x00007f5b50c01730 (40 bytes), script=/mnt/c/Users/cmb/php-dev/76850.php === Total 1 memory leaks detected === zend_mm_heap corrupted Segmentation fault (core dumped) Anantol, could you please have a look at this?

I bisected the problem and it seems to work before commit 684ce24eecc5afe7ba767e721c29ef3bb191c43c which is pcre/locale related. The locale returned by the first setlocale is de_CH.UTF-8 and I'm using openSUSE Tumbleweed 20180829. Test script: --------------- <?php function foo() { $oldlocale = setlocale(LC_CTYPE, 0); setlocale(LC_CTYPE, $oldlocale); } foo(); preg_match('/./', "a"); Expected result: ---------------- Return code 0 Actual result: -------------- Return code 1 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76850&edit=1
