Default Confused w/ GGNFS test-sieving

I'm trying to get used to using GGNFS for small test-sieving runs, but it keeps quitting with a segfault every time I run it. I'm using the latest svn commit, logs are below:


error:

Code:
../gnfs-lasieve4I14e -r best -f 40000000 -c 2000 -o out -v 
gnfs-lasieve4I14e (with asm64): L1_BITS=15, SVN $Revision: 430 $
Warning:  lowering FB_bound to 39999999.
FBsize 0+0 (deg 5), 2433653+0 (deg 1)
 Segmentation fault (core dumped)
This is occurring with many different polynomials, but the one I initially encountered this with is:

Code:
