New Comment:
Thanks for your time.
However, 8MB memory limit should be enough for phpinfo() output with zlib compression,
isn't it?
Buffer size is default. (4096)
I'll test against with current 4.1.0RC CVS and 4.2.0-dev and report result later.

Looks like it may be related to bug #13698 after all. The mbstring-auto-conversion
may be the problem here, as without it - I cannot reproduce the bug, and it appears to
work fine...

This issue does not appear to be related in any way to the bug id's 12270 and 13698...

This is most probably not a bug, at least not in the way you perceive it. With a
large output buffer - the script will indeed have to consume lots of memory. If your
memory limit does not allow this - you'll get these warnings, and in case of a debug
build - those complaints about memory being freed...
Now, there could be two authentic bugs:
(a) There may be a bug in the memory limit implementation. However, it's the same as
it has been for years, and it may be that just output buffering is exploiting it in a
way that wasn't thought of before. Generally, if the memory limit is reached, PHP
tries to bail out nicely. If somehow, PHP goes on consuming more memory, beyond 1MB
above the memory limit - it performs a hard exit(). It's possible that the shutdown
sequence causes some loop of memory exhaustion - bailout - memory exhaustion -
bailout#2 - etc., which cannot be broken. I'll take a look at it.
(b) There might be a memory leak in the zlib output compression code. Please let me
know what buffer size you use. You really shouldn't be using more than about 16KB or
so.

Problem is appearent if output is larger than output buffer size.
httpd exits with code 01 with following script
(No output)
<?php
for ($i=0; $i < 1024; $i++) echo 'abcd';
?>
but it not with
(Output is correct)
<?php
for ($i=0; $i < 1023; $i++) echo 'abcd';
?>
It exits with code 01 with more complex script w/o output, though.

Upgraded from apache 1.3.20 to 1.3.22.
httpd exited with status code 01 while running under gdb.
(gdb) run -X
Starting program: /usr/sbin/httpd -X
Program exited with code 01.
(gdb)
