From: andy at webtatic dot com Operating system: CentOS 7 PHP version: 7.0.0alpha1 Package: Reproducible crash Bug Type: Bug Bug description:PHP 7.0.0alpha1 segmentation fault when exactly 33 extensions are loaded Description: ------------ When 33 extensions would be loaded (either dynamic or static), PHP 7.0.0alpha1 segmentation faults. This doesn't appear to be any combination of 33 extensions. gdb gives the following error: Program received signal SIGSEGV, Segmentation fault. zend_startup_module_ex (module=0xa) at /home/vagrant/rpmbuild/BUILD/test/Zend/zend_API.c:1818 1818 if (module->module_started) and backtrace: (gdb) backtrace #0 zend_startup_module_ex (module=0xa) at /home/vagrant/rpmbuild/BUILD/test/Zend/zend_API.c:1818 #1 0x00000000005eb499 in zend_hash_apply (ht=ht@entry=0xa7ede0 <module_registry>, apply_func=apply_func@entry=0x5de100 <zend_startup_module_zval>) at /home/vagrant/rpmbuild/BUILD/test/Zend/zend_hash.c:1434 #2 0x00000000005de3aa in zend_startup_modules () at /home/vagrant/rpmbuild/BUILD/test/Zend/zend_API.c:1986 #3 0x000000000057d34e in php_module_startup (sf=<optimized out>, additional_modules=additional_modules@entry=0x0, num_additional_modules=num_additional_modules@entry=0) at /home/vagrant/rpmbuild/BUILD/test/main/main.c:2198 #4 0x0000000000661b9d in php_cli_startup (sapi_module=<optimized out>) at /home/vagrant/rpmbuild/BUILD/test/sapi/cli/php_cli.c:419 #5 0x0000000000428260 in main (argc=1, argv=0xa824f0) at /home/vagrant/rpmbuild/BUILD/test/sapi/cli/php_cli.c:1314 Test script: --------------- ./configure --disable-phpdbg --libdir=/usr/lib64/php --without-readline --with-libedit --cache-file=../config.cache \ --with-libdir=lib64 \ --with-config-file-path=/etc \ --with-config-file-scan-dir=/etc/php.d \ --disable-debug \ --with-pic \ --disable-rpath \ --without-pear \ --with-freetype-dir=/usr \ --with-png-dir=/usr \ --with-xpm-dir=/usr \ --enable-gd-native-ttf \ --without-gdbm \ --with-jpeg-dir=/usr \ --with-openssl \ --with-pcre-regex \ --with-zlib \ --with-layout=GNU \ --with-kerberos \ --with-libxml-dir=/usr \ --with-mhash \ --enable-dtrace \ --with-imap=shared --with-imap-ssl \ --enable-mbstring=shared \ --enable-mbregex \ --with-gd=shared \ --with-gmp=shared \ --enable-calendar=shared \ --enable-bcmath=shared \ --with-bz2=shared \ --enable-ctype=shared \ --enable-dba=shared --with-db4=/usr \ --enable-exif=shared \ --enable-ftp=shared \ --with-gettext=shared \ --with-iconv=shared \ --enable-sockets=shared \ --enable-tokenizer=shared \ --with-xmlrpc=shared \ --with-ldap=shared --with-ldap-sasl \ --enable-mysqlnd=shared \ --with-mysqli=shared,mysqlnd \ --with-interbase=shared,/usr/lib64/firebird \ --with-pdo-firebird=shared,/usr/lib64/firebird \ --enable-dom=shared \ --with-pgsql=shared \ --enable-simplexml=shared \ --enable-xml=shared \ --enable-wddx=shared \ --with-snmp=shared,/usr \ --enable-soap=shared \ --with-xsl=shared,/usr \ --enable-xmlreader=shared --enable-xmlwriter=shared \ --with-curl=shared,/usr \ --enable-pdo=shared \ --with-pdo-odbc=shared,unixODBC,/usr \ --with-pdo-mysql=shared,mysqlnd \ --with-pdo-pgsql=shared,/usr \ --with-pdo-sqlite=shared,/usr \ --with-pdo-dblib=shared,/usr \ --with-sqlite3=shared,/usr \ --enable-json=shared \ --enable-zip=shared \ --with-pspell=shared \ --enable-phar=shared \ --with-mcrypt=shared,/usr \ --with-tidy=shared,/usr \ --enable-sysvmsg=shared --enable-sysvshm=shared --enable-sysvsem=shared \ --enable-shmop=shared \ --enable-posix=shared \ --with-unixODBC=shared,/usr \ --enable-fileinfo=shared \ --enable-intl=shared \ --with-icu-dir=/usr \ --with-enchant=shared,/usr \ --enable-opcache make sudo make install cp php.ini-production /etc/php.ini mkdir /etc/php.d for mod in bz2 calendar ctype curl exif file info get text gap iconv son phar shmop simplexml sockets tokenizer xml zip;
