Try running 'make check-parallel'  :D

That's .. odd.

Does that automatic crash log include a core dump?  That should be able 
to tell you what went wrong where..

Also, run ./configure with --enable-debug as that will adjust the 
compile options to make debugging easier.

This is an example of what I use to run filters in isolation:

 # pull these two from your printers.conf
 export CUPS_URI="gutenprint53+usb://HiTi/P520L?serial=2WC4A1013968279"
 export DEVICE_URI="gutenprint53+usb://HiTi/P520L?serial=2WC4A1013968279"
 # Snag from /etc/cups/ppd or generate with cups-genppd.5.3
 export PPD="stp-dnp-p520l.5.3.ppd"
 # these don't matter but need to be set
 export id="123"
 export user="me"
 export title="image test"
 export copies="1"
 # And whatever non-default print options you want 
 export OPTIONS="PageSize=w324h576"

 # convert image to CUPSraster (only need to do this once if the options or PPD don't change)
 /usr/lib/cups/filter/imagetoraster "$id" "$user" "$title" "$copies" "$OPTIONS" image.ppm > image.raster
 # generate spool file for printer (what you probably care about)
 /usr/lib/cups/filter/rastertogutenprint.5.3 "$id" "$user" "$title" "$copies" "$OPTIONS" image.raster > image.raw
 # Send it to the printer (optional)
 cat image.raw | /usr/lib/cups/backend/gutenprint53+usb "$id" "$user" "$title" "$copies" "$OPTIONS"
