ReckiCT\JitTest::testGetFunctionAstInternalFunction fails on Windows

[tomzx]

PHP 5.6.4

Part of interest in the callstack + arguments.
Jit::parseFile($fileName = false)
Jit::getFunctionAst($name = 'strlen')

$fileName = realpath($fileName); returns the current working directory.

Since $this->parsedFiles[$fileName] (with the working path as $fileName) does not exist, it will enter the condition and attempt to read a file. In this particular case, it'll attempt to read the directory, which does not make sense. Thus, I end up with

file_get_contents(E:\GIT\recki-ct\test): failed to open stream: Permission denied
