Severe bug in grub-2.12-for-windows

[Dave Pickens]

    Hi,
      
      I am the author of Grub2Win.
      
      In order to generate kernels from a Windows environment, I rely
      heavily on the Windows version (grub-2.12-for-windows)
      
      In testing, I have discovered that the EFI 64 bit kernel generated
      by the grub-mkimage.exe module will not boot.
      The EFI 32 bit and non EFI i386-pc kernels work well and boot with
      no problem.
      
      I have submitted bug report #65072 with details, a screenshot and
      the script used to generate the kernels.
      The text of the bug report is shown below.
      
      Any help from you would be greatly appreciated as I would like to
      include the 2.12 kernels in my software soon.
      
      Many thanks,
      
      Dave Pickens

      I am testing the newly released version 2.12.
      
      Using grub-mkimage.exe to create a bootable 64 bit EFI kernel.
      
      When the kernel is loaded at boot time it gives message
      
      symbol '_stack_chk_guard' not found
      
      See the attached screenshot.
      Then the kernel aborts.
      
      I was extremely careful when generating the kernel to ensure that
      the matching libraries were used by the grub-mkimage command.
      The libraries and command are all in the same directory, so it is
      very unlikely that a mismatch occurred.
      
      This bug renders grub-2.12-for-windows useless.
      The kernel will not boot.
      
      I have also attached the Windows .bat script I used to generate
      the kernels.
      
      Note: The 32 bit i386-efi and non EFI i386-pc kernels work fine.
      The problem is strictly with the 64 bit x86_64-efi kernel.
