Is there anything I can do other than tweaking the source code?

This is a weird bug that keeps coming up. Because it once worked for me, I wonder if this is something that changed with compiler versions.

The direct fix is to simply remove the ampersand (just delete it from the brackets, i.e. [&] to []) where the error comes up.

I need to fix this with a pull request.
