Needed this for writing the test so that I can still check for errors while also testing that the compiler didn't crash

The error flag is checked after anyways so this shouldn't cause problem

This stops the segfault so it is accessing something

Alternative solution is to check the error flag ourselves and assign an empty node (Or maybe an error node?) if something goes wrong

File never failed so exit code differing is better error than files differing

…fter messages

The other stuff isn't failing for me :/ so think this is the safest option since it should keep backwards compaitability

On windows `peekExitCode` will always return 0 if read after the process is closed

Now I just check the suffix so that editing the file won't have affects
