Previous Comments: ------------------------------------------------------------------------ [2005-10-16 16:11:56] oancea at gmail dot com Description: ------------ When changing the value of the ini setting sqlite.assoc_case to 1 or 2 causes a php crash. Tested with php 5.0.4, php 5.0.5 and php 5.1.0RC1 on Mandriva Linux 2006. Reproduce code: --------------- <?php if (is_file('test.db')) unlink ('test.db'); ini_set('sqlite.assoc_case', 1); // with 2 is the same thing $query=<<<sql CREATE TABLE authors ( id INTEGER PRIMARY KEY, name VARCHAR(100), email VARCHAR(150) ); sql; $db= sqlite_open('test.db'); sqlite_query($db, $query); $_query="PRAGMA table_info(authors)"; $rs= sqlite_query($db, $_query); // if the last line is replaced by // sqlite_query($db, $_query); // will work without seg. fault, // but the is no use to do that, since we have to process the result set. Expected result: ---------------- Not a Segmentation fault anyway. Actual result: -------------- (gdb) run sqlite.php Starting program: /wwwroot/bin/php sqlite.php Reading symbols from shared object read from target memory...done.
