While trying to write a reproducer for CVE-2016-2776, I discovered

This might be due to an incomplete fix for CVE-2015-5477.  If the
entire fix is missing, you can probably reuse the CVE ID.  If not,
please let us know, and we'll assign a new ID once you have a patch.

according to [1] the fix for CVE-2015-5477 is just one line, which is applied correctly in 9.8.4.dfsg.P1-6+nmu2+deb7u6. Also 9.8.4.dfsg.P1-6+nmu2+deb7u2 crashes as well with your script, so this seems to be a different problem.

I think we are dealing with a different problem here, as Thorsten says the patch for CVE-2015-5477 seems to be applied correctly in code, yet
9.8.4.dfsg.P1-6+nmu2+deb7u11 is still affected:

The version in jessie ,9.9.5.dfsg-9+deb8u7, is unaffected.
