I have the same problem on Centos 5.2, php 5.2.11
Encoding bug using flush with zlib output handler.
To reproduce...
Turn on zlib.output_compression = On
and load a page containing the following with a browser.
<?
echo "test";
flush();
?>
the result is garbled up

If you dont use flush() works correctly.
If you dont turn on zlib.output_compression works correctly.
Note that it's not simply user config error as it works correctly
without flush().

Same here on Gentoo. Nothing was changed in configuration only PHP has
been updated to 5.2.11 and my scripts stops working.
zlib.output_compression=Off fixes issue, but also disables compression.
Maybe important, I've got updated zlib library to version 1.2.3 in the
same time.

setting zlib.output_compression to Off fixes the problem. I have no
output handlers defined. Is there anything more that might of interrest?

possibly interresting php.ini setting:
zlib.output_compression = On

Thanks for the response. As far as I know I didn't make any changes to
the compression settings. Anything specific I should look at? The
request and headers are as follows:
GET /ipinfo HTTP/1.1

application/x-ms-application, application/vnd.ms-xpsdocument,

Your hint about compression is correct. Both the requests are handled
with compression. The code using flush returns "garbage" the code not
using flush returns correct output.
