Edit report at http://bugs.php.net/bug.php?id=51492&edit=1 ID: 51492 Updated by: iliaa@php.net Reported by: naderman at naderman dot de Summary: SQLite2 query starting with a hash causes a segfault -Status: Open +Status: Wont fix Type: Bug Package: SQLite related Operating System: Ubuntu Linux 9.10 x86_64 PHP Version: 5.3SVN-2010-04-07 (SVN) New Comment: This is a bug inside SQLite 2 itself and not PHP. Previous Comments: ------------------------------------------------------------------------ [2010-04-07 10:19:03] naderman at naderman dot de Description: ------------ Running a SQLite 2 query that starts with a hash (#) causes a segmentation fault. I don't believe hashes are correct comment syntax in SQLite so the query is quite certainly invalid and should cause an error. Test script: --------------- <?php $db = sqlite_open(':memory:'); sqlite_query('#', $db); Actual result: -------------- #0 *__GI_strncpy (s1=0x7f39c2c66026 "\"", s2=0x7f3900000000 <Address 0x7f3900000000 out of bounds>, n=40) at strncpy.c:41 #1 0x000000000058c594 in sqliteSetNString (pz=0x7fffc0c6b728) at /usr/include/bits/string3.h:122 #2 0x0000000000589a7e in sqliteRunParser (pParse=0x7fffc0c6b570, zSql=0x2755908 "#", pzErrMsg=<value optimized out>) at /home/naderman/projects/php/php-src-5.3/ext/sqlite/libsqlite/src/tokenize.c:436 #3 0x000000000057edfc in sqlite_compile (db=0x2777e30, zSql=0x2755908 "#", pzTail=0x7fffc0c6b6a0, ppVm=0x7fffc0c6b698, pzErrMsg=0x7fffc0c6b728) at /home/naderman/projects/php/php-src-5.3/ext/sqlite/libsqlite/src/main.c:728 #4 0x000000000057f02b in sqlite_exec (db=<value optimized out>, zSql=0x2755908 "#", xCallback=0, pArg=<value optimized out>, pzErrMsg=<value optimized out>) at /home/naderman/projects/php/php-src-5.3/ext/sqlite/libsqlite/src/main.c:640 #5 0x00000000005695b4 in zif_sqlite_query (ht=<value optimized out>, return_value=0x2752c28, return_value_ptr=<value optimized out>, this_ptr=0x0, return_value_used=0) at /home/naderman/projects/php/php-src-5.3/ext/sqlite/sqlite.c:2087 #6 0x0000000000685d76 in zend_do_fcall_common_helper_SPEC (execute_data=0x7f39cc853050) at /home/naderman/projects/php/php-src-5.3/Zend/zend_vm_execute.h:313 #7 0x000000000067fe98 in execute (op_array=0x2753470) at /home/naderman/projects/php/php-src-5.3/Zend/zend_vm_execute.h:104 #8 0x000000000065b82a in zend_execute_scripts (type=8, retval=<value optimized out>, file_count=3) at /home/naderman/projects/php/php-src-5.3/Zend/zend.c:1194 #9 0x000000000060b5bd in php_execute_script (primary_file=<value optimized out>) at /home/naderman/projects/php/php-src-5.3/main/main.c:2260 #10 0x00000000006e1810 in main (argc=<value optimized out>, argv=<value optimized out>) at /home/naderman/projects/php/php-src-5.3/sapi/cli/php_cli.c:1192 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51492&edit=1
