[Bug 1647917] [NEW] Invalid access when opening eps with ghostscript 9.19~dfsg+1-0ubuntu6.2 and libspectre 0.2.8

[Jeremy Bicha]

Public bug reported:

1. Install the latest Ubuntu security update for ghostscript (since this
does not appear to have been released for zesty, it is a bit easier to
do this from Ubuntu 16.10 than from 17.04).

2. Install libspectre1 0.2.8-1 (from zesty or zesty-proposed).

3. Open a .eps with Evince, Ubuntu's default viewer for eps files.
Here's a test file:

https://bugs.launchpad.net/ubuntu/+source/libspectre/+bug/1348384/+attachment/4171120/+files/countrate.eps

What happens:
The .eps fails to display. If run from a terminal, this is output:

invalidaccess -7

Earlier version of libspectre (I tested Ubuntu 14.04 and 16.10) still
handle the test .eps file ok.
