Description:
------------
imap_search($connection, 'ALL') seems to be causing a segmentation fault.
The backtrace (from what I guess), seems to suggest the command is recursively calling itself to free the searchset, the same thing being called endlessly.
The php build was based on the CentOS testing php-5.2.6 rpm modified to compile php-5.2.10. php-5.2.9 did not have this issue.

The c client I'm using is the one part of CentOS 5.3, 2004g-2.2.1 I added the --enable-debug to the configure earlier, and got a php build that had a version like: PHP 5.2.10 (cli) (built: Jun 20 2009 18:09:52) (DEBUG) I'm not sure why its not adding debug information. Sorry, the proper ./configure is more like: configure \ --cache-file=../config.cache \ --with-libdir=%{_lib} \ --with-config-file-path=%{_sysconfdir} \ --with-config-file-scan-dir=%{_sysconfdir}/php.d \ --with-pic \ --disable-rpath \ --without-pear \ --with-bz2 \ --with-curl \ --with-exec-dir=%{_bindir} \ --with-freetype-dir=%{_prefix} \ --with-png-dir=%{_prefix} \ --enable-gd-native-ttf \ --without-gdbm \ --with-gettext \ --with-gmp \ --with-iconv \ --with-jpeg-dir=%{_prefix} \ --with-openssl \ --with-png \ --with-pspell \ --with-expat-dir=%{_prefix} \ --with-pcre-regex=%{_prefix} \ --with-zlib \ --with-layout=GNU \ --enable-exif \ --enable-ftp \ --enable-magic-quotes \ --enable-sockets \ --enable-sysvsem --enable-sysvshm --enable-sysvmsg \ --enable-track-vars \ --enable-trans-sid \ --enable-yp \ --enable-wddx \ --with-kerberos \ --enable-ucd-snmp-hack \ --with-unixODBC=shared,%{_prefix} \ --enable-memory-limit \ --enable-shmop \ --enable-calendar \ --enable-dbx \ --enable-dio \ --without-mime-magic \ --without-sqlite \ --with-libxml-dir=%{_prefix} \ --with-xml \ --with-system-tzdata \ --enable-debug \ --enable-force-cgi-redirect \ --enable-pcntl \ --with-imap=shared --with-imap-ssl \ --enable-mbstring=shared --enable-mbstr-enc-trans \ --enable-mbregex \ --with-ncurses=shared \ --with-gd=shared \ --enable-bcmath=shared \ --enable-dba=shared --with-db4=%{_prefix} \ --with-xmlrpc=shared \ --with-ldap=shared --with-ldap-sasl \ --with-mysql=shared,%{_prefix} \ --with-mysqli=shared,%{_bindir}/mysql_config \ --enable-dom=shared \ --with-dom-xslt=%{_prefix} --with-dom-exslt=%{_prefix} \ --with-pgsql=shared \ --with-snmp=shared,%{_prefix} \ --enable-soap=shared \ --with-xsl=shared,%{_prefix} \ --enable-xmlreader=shared --enable-xmlwriter=shared \ --enable-fastcgi \ --enable-pdo=shared \ --with-pdo-odbc=shared,unixODBC,%{_prefix} \ --with-pdo-mysql=shared,%{_prefix} \ --with-pdo-pgsql=shared,%{_prefix} \ --with-pdo-sqlite=shared,%{_prefix} \ --enable-json=shared \ --enable-zip=shared \ --with-readline \ --enable-dbase=sharedI've made a patch for it, as I'd like to have it patched in my rpms of 5.2.10.
