Summary and Info: I did a "pacman -Syu" and grub package was updated :

grub-2.00.5086-1 ---> grub 1:2.00.1282.g5ae5c54-1

so I run 2 scripts in order to reinstall grub and update configs files :

- grub-install --recheck /dev/sdc
output : "Installation finished. No error reported."

then :

grub-mkconfig -o /boot/grub/grub.cfg

and I see errors messages :

Generating grub configuration file ...
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/initramfs-linux.img
error: out of memory.
error: syntax error.
error: Incorrect command.
error: syntax error.
Syntax error at line 194
Syntax errors are detected in generated GRUB config file.
Ensure that there are no errors in /etc/default/grub
and /etc/grub.d/* files or please file a bug report with
/boot/grub/grub.cfg.new file attached.done

so it's seems that grub package has a problem, something is wrong with the file grub-mkconfig

my system: archlinux 64 bits
4 Gb ram

Steps to Reproduce:
- you must have already a grub installation ( package grub-2.00.5086-1 )
- then do a "pacman -Syu" in order to have the last grub package ( grub 1:2.00.1282.g5ae5c54-1 )
- reinstall grub ( grub-install --recheck /dev/sdX )
- regenerate the gruf.cfg file ( grub-mkconfig -o /boot/grub/grub.cfg )
- error messages will be displayed
