I was thinking whether scratch-buffers could be used in this case? That would have some minor performance impact in corner cases when the buffer needs to grow,
but otherwise it shouldn't, and would allow pretty much infinite length.

I'm not entirely sure scratch-buffers are usable in this case, though. But if they are, they sound like a better approach than alloca() to me.
