Previous Comments: ------------------------------------------------------------------------ [2015-12-16 22:25:40] maroszek at gmx dot net Description: ------------ As stated here: http://curl.haxx.se/libcurl/c/CURLOPT_DNS_USE_GLOBAL_CACHE.html and here: http://php.net/manual/en/function.curl-setopt.php CURLOPT_DNS_USE_GLOBAL_CACHE is not thread safe. This option should not get enabled by default when ZTS is enabled. And we should not allow the user to set this option, when ZTS is enabled. I attached a patch which fixes both things. Test script: --------------- Just make a lot of random requests in a lot of threads to different domains. After a while the crash will happen. Expected result: ---------------- No crash Actual result: -------------- Crash. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71144&edit=1
