git-clone causes out of memory

[Constantine <hi-angel@xxxxxxxxx>]

There's a gitbomb on github. It is undoubtedly creative and funny, but 
since this is a bug in git, I thought it'd be nice to report. The command:

	$ git clone https://github.com/x0rz/ShadowBrokersFiles

quickly fills out the RAM (e.g. 4GB of free memory for me). To recover, 
call oom-killer through Alt+SysRq+f, then switch to a TTY and back.

Git version: 2.14.2
