Description:
------------
This error happens with php 4.4.4 and php 5.2.0.

Test system:
Dual Processor Intel Xeon CPU 3.20ghz
Red Hat Enterprise 4 x86_64
glibc 2.3.4
gcc 3.4.6
apache 2.0.59
PHP 4.4.4 build flags:

./configure \
  --prefix=/opt/php-4.4.4 \
  --with-apxs2=/opt/apache-2.0.59/bin/apxs \
  --with-sybase-ct=/usr/local/sybase/OCS-12_5 \
  --enable-debug

The apache startup script exports the following env vars:
SYBASE="/usr/local/sybase"
SYBASE_OCS="OCS-12_5"
SYBASE_SYSAM="SYSAM-1_0"
LANG="en_US"

There are no errors reported from the sybase client library in the log file. I also had to hand edit ./configure because it cannot find the sybase 64bit libraries.

The below code executes correctly on our old server which ran Solaris 8, Apache 1.3.33, PHP 4.4.0 and connected to the same sybase server.

Reproduce code:
---------------
ini_set('display_errors', '1');
error_reporting(E_ALL);

$link = sybase_connect('omega', 'test1', 'pass');
$worked = sybase_select_db('dev01', $link);

$sql = "SELECT * FROM Events";
$mixed = sybase_query($sql, $link);

print_r($mixed);

Expected result:
----------------
It should print out something like the following:

Resource id #3

Actual result:
--------------
In the apache log I see the following error:

FATAL:  emalloc():  Unable to allocate 42949672961 bytes
