My guess is that pg_null_as is being freed improperly. A similar pointer is freed conditionally within pg_copy_from(). Could be related to segfault in bug 35168. Test script: --------------- // setup pg_query($db, 'CREATE TEMP TABLE temp_test_table (a INT)'); pg_query($db, 'INSERT INTO temp_test_table VALUES (1)'); // success var_dump(pg_copy_to($db, 'temp_test_table')); // success var_dump(pg_copy_to($db, 'temp_test_table', "\t")); // failure var_dump(pg_copy_to($db, 'temp_test_table', "\t", "\\\\N")); Expected result: ---------------- Three identical arrays: array(1) { [0]=> string(2) "1 " } array(1) { [0]=> string(2) "1 " } array(1) { [0]=> string(2) "1 " } Actual result: -------------- The third array is corrupted: array(1) { [0]=> string(2) "1 " } array(1) { [0]=> string(2) "1 " } array(1) { [0]=> string(2) "@�" } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51609&edit=1
