Haha, no idea, but I'd be curious to see :D

Oh, I see, thanks for testing!

So, it seems to be about g++ taking up too much memory.

Yeah, I've seen these ones, but I'm rather not sure it's the same
situation, because the issue I'm having seems to be tightly linked to
initialiser lists.  That is, I can successfully compile and run code
creating quite large arrays (e.g., std::array< std::list< char >,
10000000 >, ten million elements) if I don't use (empty) initialiser
lists.
