package error about gdb.html.tar.gz

[asmwarrior]

Hi, I found a package error, that in the page:
https://sourceware.org/gdb/current/onlinedocs/

There is a link named : gdb.html.tar.gz 19520 KB in section "Debugging with GDB"
I just download it and found that it contains all the GDB source code, is that a package error?
I think this file should only contains the html achieve of the document.

Thanks.
