We bumped into the build error while testing gcc-10 pre-release.

Here I'd like to quote from the gcc document [1] which seems best to
explain what is going on here.
"Although the size of a zero-length array is zero, an array member of
this kind may increase the size of the enclosing type as a result of
tail padding. The offset of a zero-length array member from the
beginning of the enclosing structure is the same as the offset of an
array with one or more elements of the same type. The alignment of a
zero-length array is the same as the alignment of its elements.
Declaring zero-length arrays in other contexts, including as interior
members of structure objects or as non-member objects, is discouraged.
Accessing elements of zero-length arrays declared in such contexts is
undefined and may be diagnosed."
The l_hash[0] is apparnetly an interior member to the enclosed structure
while l_entries[0] is the trailing member. And the offending code tries
to access members in l_hash[0] array that triggers the diagnose.
Given that the l_entries[0] is used to get proper alignment to access
leaf chunks, we can accomplish the same thing through the ALIGN_UP macro
thus eliminating l_entries[0] from the structure. In this way we can
pacify the warning as l_hash[0] now becomes the last member to the
enclosed structure.

Ventoy
Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files.
With ventoy, you don't need to format the disk over and over, you just need to copy the image files to the USB drive and boot it.
You can copy many image files at a time and ventoy will give you a boot menu to select them.
You can also browse ISO/WIM/IMG/VHD(x)/EFI files in local disk and boot them.
x86 Legacy BIOS, IA32 UEFI, x86_64 UEFI, ARM64 UEFI and MIPS64EL UEFI are supported in the same way.
Both MBR and GPT partition style are supported in the same way.
Most type of OS supported(Windows/WinPE/Linux/Unix/ChromeOS/Vmware/Xen...)
1200+ ISO files are tested (List). 90%+ distros in distrowatch.com supported (Details).
