ID: 25527 Updated by: sniper@php.net Reported By: suck at my-balls dot com -Status: Open +Status: Bogus Bug Type: XSLT related Operating System: OpenBSD 3.4 PHP Version: 4.3.3 New Comment: 1. Not enough info 2. Lame email address 3. It's Sablot bug. Previous Comments: ------------------------------------------------------------------------ [2003-09-13 18:55:47] suck at my-balls dot com Description: ------------ OpenBSD 3.4 with the stock apache. PHP 4.3.3 from the openbsd ports tree. (./configure --with-apxs=/usr/sbin/apxs --without-mysql --enable-xml --enable-wddx --enable-cli --with-iconv=/usr/local --with-gettext=/usr/local --enable-dio --with-pear=/var/www/pear --enable-bcmath --enable-session --enable-trans-sid --enable-calendar --enable-ctype --enable-ftp --with-pcre-regex --with-posix --enable-sockets --enable-sysvsem --enable-sysvshm --enable-yp --with-recode=/usr/local --enable-shared --disable-static --disable-rpath --with-config-file-path=/var/www/conf --enable-inline-optimization --with-pic --with-openssl --with-zlib --prefix=/usr/local --sysconfdir=/etc) xslt and other extensions are loaded as shared objects: extension=xslt.so extension=domxml.so extension=gd.so extension=mcrypt.so extension=mhash.so extension=pgsql.so extension=mysql.so Using xslt_process from a php script causes apache to seg fault. Reproduce code: --------------- $this->xh = xslt_create(); $this->arguments = array(); xslt_set_encoding($this->xh, "ISO-8859-2"); -snip- $result = @xslt_process($this->xh, $this->xml, $this->xsl, NULL, array(), $this->arguments); The call to xslt_process causes the seg fault. $this->xml and $this->xsl are set to .xml and .xsl filenames. Expected result: ---------------- I was hoping it would do what xslt_process is supposed to do, instead of crashing apache :) Actual result: -------------- [Thu Sep 11 22:02:18 2003] [notice] child pid 28749 exit signal Segmentation fault (11) [Thu Sep 11 22:02:18 2003] [notice] child pid 21161 exit signal Segmentation fault (11) Program received signal SIGSEGV, Segmentation fault. 0x1c05a300 in hashTableIterNext () (gdb) bt #0 0x1c05a300 in hashTableIterNext () #1 0x1c053d37 in XML_GetCurrentLineNumber () #2 0x6b1a249 in TreeConstructer::getCurrentLineNumber () #3 0x6b1da18 in TreeConstructer::report () #4 0x6b1ad32 in TreeConstructer::feedDocumentToParser () #5 0x6b19d48 in TreeConstructer::parseDataLineUsingGivenExpat () #6 0x6b1a050 in TreeConstructer::parseDataLineUsingExpat () #7 0x6b3def0 in Tree::parse () #8 0x6b21470 in Processor::addLineParse () #9 0x6b219a9 in Processor::readTreeFromURI () #10 0x6b1f5f3 in Processor::open () #11 0x6b26c50 in SablotRunProcessorGen () #12 0xb060184 in zif_xslt_process (ht=6, return_value=0x3c8a1a8c, this_ptr=0x0, return_value_used=1) at /usr/ports/www/php4/extensions/w-php-4.3.3-no_x11-no_bz2-no_curl-no_dba-no_dbase-no_dbx-no_filepro-no_gmp-no_imap-no_ldap-no_ncurses-no_odbc-no_pdf-no_shmop-no_snmp-no_pspell-no_sybase_ct/php-4.3.3/ext/xslt/sablot.c:590 #13 0x75b6c13 in execute () #14 0x75b6d8a in execute () #15 0x75a6596 in zend_execute_scripts () #16 0x757ca5f in php_execute_script () #17 0x75bda0e in apache_php_module_main () #18 0x75be5eb in send_php () #19 0x75be64a in send_parsed_php () #20 0x1c0373e4 in ap_invoke_handler () #21 0x1c047e2c in ap_some_auth_required () #22 0x1c048128 in ap_internal_redirect () #23 0x1c02efcf in ssl_expr_yyinput () #24 0x1c0373e4 in ap_invoke_handler () #25 0x1c047e2c in ap_some_auth_required () #26 0x1c047e88 in ap_process_request () #27 0x1c040ade in ap_child_terminate () #28 0x1c040cfe in ap_child_terminate () #29 0x1c040f88 in ap_child_terminate () #30 0x1c041635 in ap_child_terminate () #31 0x1c041b97 in main () ---Type <return> to continue, or q <return> to quit--- #32 0x1c00ec81 in ___start () #33 0x1c00ebf7 in __start () #34 0xcfbf7f04 in ??
