Bug description: Sybase module complains that date strings are not null terminated
Description:
------------
I installed a debug version of 4.3.8 to try to diagnose a different
problem and I see many error messages like:
[client 192.168.1.114] PHP Warning: String is not zero-terminated (Apr 05
2004 12:00AM \x84\xcc\x8f*ZZZZZZZA) (source:
/usr/src/php-4.3.8/Zend/zend_execute_API.c:291) in Unknown on line 0,
referer: http://(my-url)
[client 192.168.1.114] PHP Warning: String is not zero-terminated (Apr 05
2004 12:00AM \x84\xcc\x8f*ZZZZZZZA) (source:
/usr/src/php-4.3.8/Zend/zend_execute_API.c:291) in Unknown on line 0,
referer: http://(my-url)
#1: It isn't very helpful to not print the actual page the error is on.
I'm assuming the "Unknown" would be the page, but it's odd that it can
print the referrer.
#2: I've tracked it down to a page that retrieves marks from a sybase
database on another server. Those dates that you see in the above are the
dates the student took her tests.
#3: These errors only appear in debug mode.
#4: With either the debug or the normal php, when I print the string there
are no extraneous characters.
#5: No extraneous characters appeared and no warning appeared in a perl
script that pulled and displayed the same information.
#6: My config:
./configure --build=i386-redhat-linux --prefix=/usr --exec-prefix=/usr
--bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc

Reproduce code:
---------------
$dbsy = startSyb(); // My connection details are hidden here.
$select = "SELECT date_completed ".
"FROM student_academic";
$handle = $dbsy->prepare($select);
$result = $dbsy->execute($handle, array());
while ($row = $result->fetchRow(DB_FETCHMODE_ASSOC)) {
}
Expected result:
----------------
Nothing, it shouldn't produce any output.
Actual result:
--------------
Many errors messages like these:
