[Bug 775377] Re: grub-mount assert failure: *** glibc detected *** grub-mount: free(): invalid next size (fast): 0x08d25b98 ***

I reproduced this bug by adding an additional menuentry in file
'/etc/grub.d/40_custom'.

Previous version of the file (no bug):

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.


New version of the file, producing the bug:

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

menuentry ‘Windows 10 msdos2′ {
set root='(hd0,msdos2)’
chainloader +1
}


Finally, I solved the bug by creating a new file '/etc/grub.d/42_custom' and put the new menuentry there...

Hope this helps.
