2GB File limit?

After aria2 downloaded 2147488918 bytes of a larger file over http it crashed:

```aria2c: FileEntry.cc:114: int64_t aria2::FileEntry::gtoloff(int64_t) const: Assertion offset_ <= goff' failed.```

I am using `aria2 version 1.18.5`
latest pacman package on Arch Linux 3.13.7-1-ARCH x86_64
