New Comment:
Apparently it happened because your kernel killed the process that
started to consume too much memory.
Not much we can do about it.
Use --enable-memory-limit and you'll be able to set memory limit and
see informative messages when you rich it.

Of course that is correct. But even then the script should not just
terminate without a message. And that is possible with this call. I
once had an out of memory message with my test script, but when I tried
to find out under which conditions str_pad outputs the message or
silently dies it disappeared and I could not make it appear again. In
the script where I discovered this behavior the out of memory message
never appeared and it was really hard to find out why the script did
not print anything anymore.

There are 1000 and 1 other ways too to consume all the available
memory. Just don't do it.

Using -INF as the length of the target string is always impossible. I
think this value should not be accepted instead of trying to allocate
this much memory.
And there still remains the problem that PHP silently terminates the
script without printing an error. I only found the reason why my script
dies in the apache log.

You're knowingly consuming all the memory available.
How exactly PHP should understand that you meant something else?

Description:
------------
str_pad should check it's parameters. With wrong parameters it is
possible to cause an out of memory error. This problem also sometimes
causes the PHP script to die completely and only leave an error in the
apache error log, no out of memory error is reported by PHP.
Reproduce code:
---------------
<?
str_pad("", log10(0), " ");
?>
Expected result:
----------------
Warning or error reported by PHP about wrong usage of str_pad for
better debugging, not just an our of memory error or silent death of
the PHP script.
Actual result:
--------------
Error in the apache log:
Allowed memory size of 8388608 bytes exhausted (tried to allocate 10
bytes)
