Nobody should try this at home. :)
Definately eats all memory and eventually crashes.
Here's what I got in error_log:
PHP Fatal error: Allowed memory size of 1603177144 bytes exhausted at
/usr/src/php/php5/ext/zlib/zlib.c:623

Let me clarify some more, here's some more ob_start
calls that you can substitute into the reproduce code
given:
These work OK:
ob_start();
ob_start(null, 2048);
ob_start(null, 1024);
ob_start('ob_gzhandler');
These don't work:
ob_start('ob_gzhandler', 1024);
ob_start('ob_gzhandler', 2048);
ob_start('ob_gzhandler', 1);

Pretty convinced this occurs whenever chunking occurs,
irrespective of what the chunk size is. Setting it to
something silly like 1 also has the same problem, for
example.
I also confirmed again the same behaviour on a Mac OS X
(10.3.8) machine, with its default php 4.3.10 setup over
Apache 1.3.33, zlib 1.1.4. Configure command is just
what's default on os x, but if you don't have an os x
machine handy, it's:
'/SourceCache/apache_mod_php/apache_mod_php-17.5/php/
configure' '--prefix=/usr' '--mandir=/usr/share/man' '--
infodir=/usr/share/info' '--with-apxs' '--with-ldap=/
usr' '--with-kerberos=/usr' '--enable-cli' '--with-zlib-
dir=/usr' '--enable-trans-sid' '--with-xml' '--enable-
exif' '--enable-ftp' '--enable-mbstring' '--enable-
mbregex' '--enable-dbx' '--enable-sockets' '--with-
iodbc=/usr' '--with-curl=/usr' '--with-config-file-
path=/etc' '--sysconfdir=/private/etc'
The php.ini is untouched from defaults.

You can always make the chunk size smaller than 2048?
Or doesn't this problem occur then?

Sorry, it's my sysadmin that set up those
configure variables....
Anyway, we used phpinfo() for example code because it
outputs something larger than the example chunk size I
was using of 2048 bytes. I could manually write out
more than 2048, but that probably wouldn't be as concise
for bug reporting.
The problem we have specifically arises when the
ob_gzhandler attempts to send out chunks.
