Open an existing text file (insert some crap before) like:

$output = fopen("test.txt", "a"); #we want append something

Here is the problem:

$position = ftell($output); #returns always 0 and not the real fileposition!!!

fputs($output, "test"); #but this works without any problems (it has the real fileposition, but ftell gets the false one)

I found this bug only on windows systems, not on linux.
