 PHP Version:      5.1.2
 New Comment:

Please try this patch:
http://tony2001.phpclub.net/dev/tmp/bug36113.diff

The field type you're using (TIMESTAMP) is not supported by the library
PHP uses to work with DBF files, so you should get a nice error message
in this case.
I don't use DBase, so please test this patch with supported fields,
just to make sure it doesn't break anything. Thanks.

Description:
------------
Reading records from a specific dBase file causes the following error
message:

*** glibc detected *** malloc(): memory corruption: 0x09efb7d0 ***
Aborted

However, if dbase_get_header_info() is called before the reading of
records, then a different error occurs:

*** glibc detected *** free(): invalid next size (fast): 0x08c4b270
***
Aborted

You can download the file causing the issue:
www.kermodebear.org/php_bug_data/sample.DBF

I thought that the file may be corrupted, so I downloaded three
different software packages ('DBF View', 'DBF Viewer 2000', 'DBF
Manager') and each of them was able to view the data without a problem.
I'm fairly certain that the file itself is not corrupt. Even if it is,
PHP should not cause these kinds of errors; The dbase_get_record
function should return false on error.

PHP version is 5.1.2;
./configure --enable-dbase

Reproduce code:
---------------
<?php
$h = dbase_open( 'sample.DBF', 0 );
// Uncomment the line below for a different error.
// dbase_get_header_info( $h );
for( $i = 1; $i <= dbase_numrecords( $h ); $i++ ) {
    dbase_get_record( $h, $i );
}
?>


Expected result:
----------------
No output at all; The file should be opened, all records should be
read, and the script should end.

Actual result:
--------------
[EMAIL PROTECTED] cli]$ ./php test.php
*** glibc detected *** malloc(): memory corruption: 0x09efb7d0 ***
Aborted

With dbase_get_header_info() called before fetching records:

[EMAIL PROTECTED] cli]$ ./php test.php
*** glibc detected *** free(): invalid next size (fast): 0x091f60b8
***
Aborted
