Bug #12450: Segfaults if recode is loaded after mysql or imap

From: troels@arvin.dk Operating system: Red Hat Linux 6.2 PHP version: 4.0.6 PHP Bug Type: Recode related Bug description: Segfaults if recode is loaded after mysql or imap PHP segfaults if recode.so (php's recode extension as a shared library) is loaded _after_ the imap or mysql extensions. Re-ordering the php.ini file so that the "extension=recode.so" line is the first "extension=..."-line stops the segfaults. Recode versions tested: 3.5d, 3.6. PHP versions tested: 4.0.6. config.nice: ============ #! /bin/sh # # Created by configure "./configure" \ "--prefix=/usr" \ "--libdir=/usr/lib/php4" \ "--includedir=/usr/include" \ "--datadir=/usr/share/php" \ "--with-config-file-path=/etc" \ "--enable-discard-path" \ "--enable-inline-optimization" \ "--enable-magic-quotes" \ "--enable-track-vars" \ "--enable-memory-limit" \ "--enable-wddx" \ "--enable-bcmath" \ "--enable-sigchild" \ "--with-xml" \ "--with-mm" \ "--with-openssl" \ "--enable-ftp=shared" \ "--enable-exif=shared" \ "--with-gd=shared,/usr" \ "--with-ttf" \ "--enable-gd-imgstrttf" \ "--with-png-dir=/usr" \ "--with-jpeg-dir=/usr" \ "--enable-sysvsem=shared" \ "--enable-sysvshm=shared" \ "--enable-shmop=shared" \ "--with-unixODBC=shared" \ "--with-mysql=shared,/usr" \ "--with-ldap=shared" \ "--with-pgsql=shared" \ "--with-gettext=shared" \ "--with-pspell=shared" \ "--with-snmp=shared" \ "--enable-ucd-snmp-hack" \ "--with-sybase-ct=shared,/usr" \ "--with-pdflib=shared" \ "--with-oci8=shared" \ "--with-swf=shared,/home/troels/rpm/BUILD/php-4.0.6/swflib" \ "--enable-sockets=shared" \ "--with-gmp=shared" \ "--with-dom=shared" \ "--with-qtdom=shared,/usr/lib/qt-2.3.0" \ "--with-iconv=shared" \ "--with-curl=shared" \ "--enable-apc=shared" \ "--with-ming=shared" \ "--with-imlib=shared" \ "--with-recode=shared" \ "--with-zlib=/usr" \ "$@" php.ini: ======== extension_dir = /usr/lib/php4 ;; Global PHP defaults warn_plus_overloading = On ; warn if the + operator is used with strings track_errors = On ; Store the last error/warning message in $php_errormsg (boolean) track_vars = On ; enable the $HTTP_*_VARS[] arrays, where * is one of magic_quotes_gpc = On ; magic quotes for incoming GET/POST/Cookie data ; many people think that the system is a pain in the ; a**, but it probably does represent a security ; feature for in-experienced PHP developers.
