You've run without the -jX option of make?  The make process can be 
deceiving when there is an error and -j8 option.

Anyway, I suspect this is a figure generation problem.  The file 
interpft.pdf is a figure, not a bigger document.  That pdf-print is 
using Mesa on your system?   (I.e., first creates an EPS file that is 
used to create the PDF file?  On my system the EPS is just prior to the PDF:

-rw-r--r-- 1 root root 14496 Dec 29 18:16 interpft.eps
-rw-r--r-- 1 root root  5686 Dec 29 18:17 interpft.pdf

so I'm guessing that's how it works.)  This looks like the long-standing 
occasional-crash-during-print issue of yester-year.

I noticed recently when reviewing this bug report:

https://savannah.gnu.org/bugs/?52781#comment3

that rescaling of the Qt and FLTK windows (i.e., drag the lower-right 
corner around via mouse) looks very poor, flashing between white and 
black backgrounds.  It's supposed to be white background all the time, 
but I'm recalling that flashing black background a trait similar to the 
bug I noted above--just a vague memory at this point.  How does the 
rescaling of Qt and FLTK figures look for you?
