Looks like the whole file got "touched" in the latest commit (maybe the encoding change or the EOL character). Try to keep the encoding on all file to be UTF-8 and EOL to be LF when pushing (but can be CRLF when checking out on Windows). Please check whether the git config option on Windows and Linux are consistent.

With that said, sometimes git does the strangest diff and it's out of our control (could be the case here).

Funnily enough, my OpenAL audio layer fixes a bug where when opening the audio a second time it crashes the entire game. |

Excuse me if I speak prematurely, but I stumble upon this and it hurts my eyes. It is never valid to stackalloc and let the pointer escape the current method. data is implicitly discarded and will be reused for method calls immediately upon return from this method. This buffer should probably be a rented buffer and perhaps also allocated from the pinned object heap, or allocated using NativeMemory, since I assume it will be used for native interop and/or hardware.

The buffer will be used asynchronously, but it won't be pinned when it is used anymore, since the fixed statement is exited. To keep the buffer pinned, allocate it pinned, or from native memory, or use GCHandle.Alloc(buffer.Value, GCHandleType.Pinned) and then keep the GCHandle around and call Free on it once the buffer no longer needs to be pinned.

Sorry for derailing the conversation slightly, but since we have you here, @ericwj can you quickly take a look at this comment we left a while ago on something you wrote #2393 (comment)
