[Bug 1627608] Re: resize2fs crashed with SIGSEGV in ext2fs_extent_translate()

[Theodore Ts'o]

Known problem, fixed in e2fsprogs 1.42.2 or 1.42.3 in commit:

commit 3d6fc974831a360aee460e54c442538445f3017c

    resize2fs: fix crash when there is an ea block and no blocks to migrate
    
    This fixes a bug introduced in 1.43 by commit fb47b94fffc: "resize2fs:
    rewrite extent/dir/ea block checksums when migrating".  If there is an
    extended attribute block and there are no blocks that need to migrate,
    we will crash.
    
    The bug was caused by a botched De Morgan's transformation.

Note that e2fsprogs 1.43.3-1 is in Debian unstable, and the only reason why it's blocked from entering testing for the last three weeks is because of the glibc 2.24 transition.
