[Pkg-puppet-devel] Bug#962784: facter aborts with free(): invalid pointer

[Russ Allbery]

Package: facter
Version: 3.11.0-4.1
Severity: grave

facter no longer works at all on amd64.  When invoked, it dies with
an invalid pointer error:

% facter
free(): invalid pointer
Aborted (core dumped)

gdb backtrace:

This also renders Puppet unusable.
