Well it seems there is some segfaulting in some of the test cases:

For example test 0485:

Starting program: /root/pspp-0.8.3/src/ui/terminal/.libs/pspp -O format=csv 
0485/means-hg.sps
[Thread debugging using libthread_db enabled]

(Note it is _normal_ to get sigill from openssl and having to continue).
Normal can be weird.

c is NULL in this call it seems, so dereferencing it seems like a bad idea.
