Public bug reported:
Description: Ubuntu 14.04.3 LTS
Release: 14.04
grub2:
Installed: (none)
Candidate: 2.02~beta2-9ubuntu1.3

I think that the grub2 needs to work for many grub shell commands.
But critical error is occurred as follow.
Bug scenario is as following.
- at the grub menu, press C key.
- enter "linux /vmlinuz" command to "grub>" shell
- enter above command once more.
- grub2 does not response.
I traced the code lines.
So the grub2 is entered and never ended a loop at the
grub_core/lib/relocator.c, free_subchunk function.
And I could not skip this loop, because if i skip this loop, the /proc/cmdline
is broken.
