If I allow the open_basedir restriction to pass,
I get now random segfaults :
Program terminated with signal 11, Segmentation fault.

I already use this snapshot. And it still happens.
I'll post soon more info. I'm compiling now a debug version.

Please try using this CVS snapshot:

Note that this bug is similar to a other bug,
http://bugs.php.net/bug.php?id=19292
It's not the same bug. There were some checks wrong
in fopen_wrappers.c. This is fixed in cvs.
This bug does show similar results as 19292,
but the source of the problem is completly different.
This a webserver with ~400 virtual servers, ~100
have php enabled.
I see the bug happen if I access frequently
pages of customer 1 (php enabled) and at the same time
customer 2.

I've done this change in main/fopen_wrappers.c to see what
happens:
- php_error(E_WARNING, "open_basedir restriction
- in effect. File is in wrong directory");
+ php_error(E_WARNING, "open_basedir: File should
+ be in %s, but is in %s file (%s)",
+ pathbuf, path,
+ zend_get_executed_filename(TSRMLS_C));
let's say pathbuf=$a, path=$b,
zend_get_executed_filename=$c
As you see $a (which is PG(open_basedir)), should be
identical to the path without added filename of both
$b and $c.
The error is random. Sometimes $a and $c are correct,
and $b is plain wrong (from a previous request). Sometimes
$a and $c are correct, and $b is wrong.

This bug is critical and not fixed in cvs. I just tried
the newest snapshot and it's not fixed.
