Tests 10-12 fail

[hepcat72]

I don't know if this is specific to my system (macOS Catalina 10.15.6), but tests 10-12 fail due to a segfault (on master):

sh: line 1: 98519 Segmentation fault: 11  ../fastq-multx -H -v ' ' -l in/multx/master-barcodes.txt in/multx/mxtest-h_1.fastq in/multx/mxtest-h_2.fastq -o tmp/multx.t.R0jAb/mxout_%_1.fq -o tmp/multx.t.R0jAb/mxout_%_2.fq > tmp/multx.t.R0jAb/test4.out 2> tmp/multx.t.R0jAb/test4.err

Hmmm, after the latest merge, this doesn't seem to be an issue, however with this version, test 8 fails because the standard output rows are in a different order. Weird. I assume there's some sort of hash scheme or something where the traversal of elements can change...

After looking into this, I believe that the segfaults are from compiling without doing a make clean first. The segfaults for these tests go away if I recompile after doing a make clean.
