My /home dir isn't writable by anyone. So how could it work? And what
does setting those permissions on strace help to debug this?

Jani,
Is bug reproducing ONLY with using "set execution bit"!
Simple way test with strace output:
1. Temprorarly set "chmod 6755" to /usr/bin/strace binary for correct
test.
2. Create simple CONSOLE test.php file and place to /home/1/ directory
(owner should be root.root):
#!/usr/bin/php -q
<?php
if (!file_exists("/home/1/2/3")) mkdir("/home/1/2/3",0700,true);
?>
3. Run this script under any unprivileged user with next cmd: "su -
someuser -c "/usr/bin/strace /home/1/test.php"
First run test.php create directory /home/1/2 and /home/1/2/3
successfully with "someuser" owner and 0700.
Second run test.php script must be finish w/o any messages, because
directory already exists, but function file_exists() incorrectly fulfils
and produces that the directory does not exist, though it is.
Try it!
If something else is not clear, I will explain more in detail.)

Your report is quite confusing. You talk about creating /home/user/2/3
directories (note the missing 1?) but your straces show quite different
outputs. Please, come up with _simple_ way to reproduce this. Simple
meaning ONE php (and PHP ONLY!) file.

Added -D__USE_FILE_OFFSET64 to CFLAGS and re-compile all php stuff.
Example of compilation (correct?):

Did you or did you not compile using the LFS flags?
------------------------------------------------------------------------
[2009-07-25 20:20:52] rusxakep at gmail dot com
No, isn't LFS bug.
I'm run test php from LFS bug notes. mkdir working fine. Directory has
been created successfully.)
