confirmed with ./configure --disable-all --disable-cli --with-zlib
both with cgi and fastcgi
good:
HTTP_ACCEPT_ENCODING=gzip php-cgi test.php |md5sum

bad:
HTTP_ACCEPT_ENCODING=gzip php-cgi test.php |md5sum

(gdb) br 720
Breakpoint 2 at 0x805d6e5: file /home/xuefer/src/php4/ext/zlib/zlib.c,
line 720.
(gdb) r
#0 php_do_deflate (str_length=2, p_buffer=0xbffff028,
p_buffer_len=0xbffff02c, do_start=1 '\001', do_end=1 '\001')
at /home/xuefer/src/php4/ext/zlib/zlib.c:720
(gdb) p outlen-zlib_globals.stream.avail_out
$8 = 10
(gdb) p buffer[outlen-zlib_globals.stream.avail_out]
$9 = 50 '2'
(gdb) step
724 *p_buffer = buffer;
(gdb) p buffer[outlen-zlib_globals.stream.avail_out]
$10 = 0 '\0'
the 2 is exactly what i see in httpwatch that get "lost" with the patch
applied
test result by php->lighttpd->httpwatch is at:
ftp://211.92.88.40/pub/phpbug/test.php.response.txt

It doesn't make any difference with/without the patch for bug #34191
(so I don't think it really broke anything)
Try with the shortest possible configure line:
# ./configure --disable-all --disable-cli --with-zlib

Can you replicate in any other SAPI, I don't have fastcgi sapi
installed anywhere.
