From: maroszek at gmx dot net Operating system: Linux, MacOS PHP version: master-Git-2020-04-10 (Git) Package: *General Issues Bug Type: Bug Bug description:ZTS builds do not properly respect max_execution_time Description: ------------ Tested against today's master. Also affects 7.x Only affects Linux and MacOS. Windows builds work fine. Please see my simple ZTS example: https://gist.github.com/paresy/3cbd4c6a469511ac7479aa0e7c42fea7 Compile: g++ php.cpp -Imain -ITSRM -IZend -I. --std=c++11 -Llibs -lphp -lresolv -ldl -pthread I used a minimal PHP build: ./configure '--disable-fpm' '--disable-cgi' '--disable-cli' '--enable-embed=static' '--enable-maintainer-zts' '--disable-all' Adding '--disable-zend-signals' does not change the result.
