It works for both script and can display phpinfo(). (It was not working before, at least when 4.1.0RC1 is released.) output.c has not been changed. It seems real problem was in some other place.

What do you mean by output.c not being changed? 4.1.0RC1 and HEAD have different output.c's...

I didn't compare output.c... but, I had almost the same behavior with 4.1.0 and 4.2.0 when I tested it. But I didn't have problem with 4.2.0 today.

Can you try to apply the patches at http://cvs.php.net/diff.php/php4/main/output.c?ws=0&r1=1.75&r2=1.77&ty=u to 4.1.0RC1, and see if the problem goes away? It should apply cleanly, except for a meaningless $Id conflict.

I tried and it *works*. Now 4.1.0RC CVS works really well so far, but more tests are needed.

The 4.0.7 codebase did not support multiple layers of internal/chunked output buffering, so mixing output buffering and mbstring-auto-encoding did not work.

Usually, I don't use zlib compression. I noticed the problem when 4.0.7RC is relased. It seems zlib output compression is working now. (I'm testing with --enable-mbstr-enc-trans) -- Yasuo Ohgaki
