Danack, thanks for your input. I have solved the problem - it was indeed one of the custom patches
that was faulty, causing stat to return a bit unexpected value 2, that came from errno by mistake.

I believe that is correct.

I believe the return values mirror those of standard system stat calls - 0 indicates success, other
values a errors. http://linux.die.net/man/2/stat
If you're not seeing the error on git 5.5.32, then you'll need to isolate where the error
has been introduced as we are unable to reproduce it.

Seems that git 5.5.32 works just fine, as expected. I do have other patches inside, as this is
redhat based rpm. Sorry, off I go to check further. But still I do not understand how could it
possibly work with this switch/case?
When file does not exist, should -1 as 'non-statable stream' be expected, or some other
error code?

I have patched my server with same check as in 5.2.17 and it now works flawlessly. Could somebody
explain how could this actually work?
Is it php_stream_stat_path_ex() supposed to return 0 if file is not found? This code just
doesn't seem right.

Please can you confirm that you don't have any security modules active that would prevent
creation of new files - such as SELinux or Suhosin?
I think it is far more likely that it is some problem unique to your computer rather than a general
bug with copy().
