Previous Comments: ------------------------------------------------------------------------ [2007-06-06 23:58:31] riverfr0zen at elitemail dot org ha. of course, i violate the first instruction :) here it is with beginning and ending php tags. <?php print "begin\n"; function startElement(){} function endElement(){} $feed = fopen('http://feeds.feedburner.com/thr/film', "r"); if ($feed) { $_parser = xml_parser_create(); xml_set_element_handler($_parser, "startElement", "endElement"); xml_set_character_data_handler($_parser, "characterData"); while ($data = fread($feed, 4096)) { if (xml_parse($_parser, $data, feof($feed)) !== 1) { print xml_error_string(xml_get_error_code($_parser)) . "\n"; print xml_get_current_line_number($_parser) . "\n"; } } fclose($feed); xml_parser_free($_parser); } print "end\n"; ?> ------------ if you comment out print xml_get_current_line_number($_parser) . "\n"; the script successfully prints out "end". but if it is left there, it never arrives, and gets a segmentation fault instead. ------------------------------------------------------------------------ [2007-06-06 20:21:21] riverfr0zen at elitemail dot org Note: Commenting out the line print xml_get_current_line_number($_parser) . "\n";" in the simple script above allows the script to complete execution without a seg fault. ------------------------------------------------------------------------ [2007-06-06 20:18:33] riverfr0zen at elitemail dot org function startElement(){} function endElement(){} $feed = fopen('http://feeds.feedburner.com/thr/film', "r"); if ($feed) { $_parser = xml_parser_create(); xml_set_element_handler($_parser, "startElement", "endElement"); xml_set_character_data_handler($_parser, "characterData"); while ($data = fread($feed, 4096)) { if (xml_parse($_parser, $data, feof($feed)) !== 1) { print xml_error_string(xml_get_error_code($_parser)) . "\n"; print xml_get_current_line_number($_parser) . "\n"; } } fclose($feed); xml_parser_free($_parser); } ------------------------------------------------------------------------ [2007-06-06 20:09:47] [EMAIL PROTECTED] Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2007-06-06 19:47:23] riverfr0zen at elitemail dot org Here's the backtrace: (gdb) bt #0 0x081c7fdd in normal_updatePosition (enc=0x8394560, ptr=0x8d7a000 <Address 0x8d7a000 out of bounds>, end=0x8d67e5d " Technique of the American Commercial.\"</description>\n</item>\n<item>\n<title>'Golden' shines for Disney</title>\n<pubDate>2007-06-06</pubDate>\n<guid isPermaLink=\"true\">http://www.hollywoodreporter.com/h"..., pos=0x8cbe948) at xmltok_impl.c:1747 #1 0x081b7afe in php_XML_GetCurrentLineNumber (parser=0x8cbe7c0) at /usr/local/src/php-4.4.7/ext/xml/expat/xmlparse.c:1571 #2 0x081b54c5 in zif_xml_get_current_line_number (ht=1, return_value=0x8d5f0ec, this_ptr=0x0, return_value_used=1) at /usr/local/src/php-4.4.7/ext/xml/xml.c:1437 #3 0x082291f2 in execute (op_array=0x8cdab84) at /usr/local/src/php-4.4.7/Zend/zend_execute.c:1681 #4 0x08229498 in execute (op_array=0x8cced9c) at /usr/local/src/php-4.4.7/Zend/zend_execute.c:1725 #5 0x08229498 in execute (op_array=0x8a71d3c) at /usr/local/src/php-4.4.7/Zend/zend_execute.c:1725 #6 0x08229498 in execute (op_array=0x8a7555c) at /usr/local/src/php-4.4.7/Zend/zend_execute.c:1725 #7 0x08229498 in execute (op_array=0x8a73204) at /usr/local/src/php-4.4.7/Zend/zend_execute.c:1725 #8 0x08229498 in execute (op_array=0x848ec3c) at /usr/local/src/php-4.4.7/Zend/zend_execute.c:1725 #9 0x08229498 in execute (op_array=0x8842254) at /usr/local/src/php-4.4.7/Zend/zend_execute.c:1725 #10 0x08229498 in execute (op_array=0x8843e64) at /usr/local/src/php-4.4.7/Zend/zend_execute.c:1725 #11 0x08229498 in execute (op_array=0x8841b44) at /usr/local/src/php-4.4.7/Zend/zend_execute.c:1725 #12 0x08229498 in execute (op_array=0x8488c1c) at /usr/local/src/php-4.4.7/Zend/zend_execute.c:1725 #13 0x08229498 in execute (op_array=0x848859c) at /usr/local/src/php-4.4.7/Zend/zend_execute.c:1725 #14 0x08212d7d in zend_execute_scripts (type=8, retval=0x0, file_count=3) at /usr/local/src/php-4.4.7/Zend/zend.c:939 #15 0x081d9897 in php_execute_script (primary_file=0xbfc2275c) at /usr/local/src/php-4.4.7/main/main.c:1757 #16 0x082314b4 in main (argc=2, argv=0xbfc22844) at /usr/local/src/php-4.4.7/sapi/cli/php_cli.c:838 (gdb) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
