Whilst doing some testing using a small subset of b-vector directions, I came across the following error whilst using dirorder

dirorder: [SYSTEM FATAL CODE: SIGSEGV (11)] Segmentation fault: Invalid memory access

Using the commandline

diroder -cartesian /tmp/bvec_test /tmp/bvec_out

where bvect_test was a simple bvec array generated from dirgen as follows:

# command_history: dirgen -cartesian 4 /tmp/dirs2  (version=3.0.2)
-0.768068368363638 0.430205845005412 -0.474335232132717

0.126952687168782 -0.0878776968375553 -0.988008363132191

Presumably this is related to the small amount of directions?
