Edit report at https://bugs.php.net/bug.php?id=68922&edit=1 ID: 68922 Updated by: laruence@php.net Reported by: mail at tomsommer dot dk Summary: Crash with setlocale LC_ALL and curl errors with special chars -Status: Open +Status: Feedback Type: Bug Package: Reproducible crash Operating System: CentOS 6 PHP Version: 5.6.5 Block user comment: N Private report: N New Comment: Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open".

Previous Comments: ------------------------------------------------------------------------ [2015-01-27 16:23:00] mail at tomsommer dot dk Description: ------------ Settings <?php setlocale(LC_ALL, 'danish') ?> and running a curl request against a hostname that returns a special timeout (firewall block), makes PHP segfault. If one does NOT use LC_ALL, but LC_MESSAGES or all of the LC_*, it does not crash. It _only_ happens for LC_ALL Test script: --------------- Testing requires one to run curl from a host that is blocked by firewall to the remote host. Cannot provide test script, hope strace is enough. Can only reproduce with mod_php5, and not in CLI, perhaps due to environment variables. Actual result: -------------- stat("/var/www/example.com/vendor/guzzlehttp/ringphp/src/Core.php", {st_mode=S_IFREG|0644, st_size=11015, ...}) = 0 rt_sigaction(SIGALRM, NULL, {SIG_DFL, [], SA_RESTORER,
