Hi,
I just noticed that std.zip will throw an exception if the source files
exceeds 2 GB.
I am not sure whether this is a limitation of zip version 20 or a bug.
On wikipedia a
size limit of 4 GB is mentioned. Should I open an issue?

I think it's inherent in the zlib API. I haven't used all of the
library, but the portion I did use (using zstream) uses uint for buffer
sizes.
