When squashfs support is enabled, the build fails with:
../grub-2.02/grub-core/fs/squash4.c: In function 'direct_read':
../grub-2.02/grub-core/fs/squash4.c:868:10: error: 'err' may be used uninitialized in this function [-Werror=maybe-uninitialized]
if (err)
^
cc1: all warnings being treated as errors
Makefile:7272: recipe for target 'grub-core/fs/libgrubmods_a-squash4.o' failed
Upstream-Status: Pending (should be fixed in gnulib which is then rarely updated in grub)
