Description:
------------
As i migrated from php4 (4.3.9) to php5 (5.0.5, 5.0.4) every file system function (fopen, dba_open, etc) cannot read/write files. Empty file can be created - but can`t write any byte there.

Not using any loaders or encoders or similar modules.

When recompiled back to 4.3.9 all works fine. The same happens when compiled as apache module - 4.3.9 works fine, 5.0.5 and 5.0.4 not.

Reproduce code:
---------------
Example can be found here - http://paste.php.lv/2785

compile script:
export LDFLAGS=-liconv && ./configure
make
make install

Linux libc-2.3.2

gcc -v

Expected result:
----------------
Expecting file `haha` to be created with contents `aa`. Also db4 database with some entries.

Actual result:
--------------
fopen() reports `failed to open stream: Inappropriate ioctl for device`

dba_open() reports `Driver initialization failed for handler: db4`
