Using cscope with VIM: adding database returns errno 75

Question

I've got a pretty large cscope.out database (over 2GB) and an inverted index of over 1GB, and when I issue the command :cscope add "path to database", I get the following error:

E563: stat("path to database") error: 75

Looking at the source code, it seems to return the errno, where 75 means value too large for defined data type.

How can I get it to load my db?

32 bit vim imposes a 2GB limit on cscope databases. Use 64 bit vim to overcome this limitation.
