Cluster.split bus error

I am using version 1.42.1. Why do I get bus error (core dumped)?
This is the command that I had run:

cluster.split(fasta=JNM.trim.contigs.good.unique.good.filter.unique.precluster.pick.pick.fasta, count=JNM.trim.contigs.good.unique.good.filter.unique.precluster.denovo.vsearch.pick.pick.count_table,, splitmethod=classify, taxlevel=4, cutoff=0.03)

I suspect this is a memory issue, but we had a bug in the count table remove functions that was causing similar problems. The count table bug has been fixed in version 1.42.3. Can you give it a try, If the issue persists, can you send your logfile and input files to so I can take a closer look for you?
