Bug#882507: ext2fs: assertion error

[Bill Blough <devel@blough.us>]

Package: hurd
Version: 1:0.9.git20170507-1
Severity: normal

Running debian-hurd-20170613.img under KVM, I'm frequently getting the
following assertion error:

ext2fs: ../../libshouldbeinlibc/refcount.h:171 refcounts_ref: Assertion
'! (r.hard == 1 && r.weak == 0) || !"refcount detected use-after-free!"'
failed.

This seems to happen randomly when doing package builds, etc., and
causes the entire system to freeze, requiring hard reboot of the VM,
fsck, etc.
