Package: e2fslibs
Version: 1.42~WIP-2011-07-02-1
Severity: important
With this version of e2fslibs, dump 0.4b44-1 is a total loss: it fails
with SIGFPE during pass IV.
An example run:

(This wasn't the filesystem, or even the machine, on which I originally
noticed the problem: in fact, it's a 32-bit installation, though it
behaves in the same way, and it's the first filesystem I tried. I'd
already downgraded ibanez when I started writing this report.)
Initially suspecting a problem with dump, I attempted to build it from
source, but that failed because the e2fslibs headers have changed
incompatibly:

I downgraded e2fslibs-dev (and hence e2fslibs too), and built dump OK.
The resulting dump binary then ran fine, as did the (unchanged)
installed dump binary.
Severity `important' because this `has a major effect on the usability
of a package [in this case dump], without rendering it completely
unusable to everyone [I suspect, without testing, that restore still
works].'
