Segmentation fault

Hi, there. I have some problems using fastool.
when I used the following code:
fastool --illumina-trinity --to-fasta <(zcat 2.1.clean.fastq.gz) > 2.1.fasta &
it report the error below:
[2]+ Segmentation fault (core dumped) fastool --rev --illumina-trinity --to-fasta <(zcat 2.2.fastq.gz) > 2.2.fasta.
But I can run fastqc on my input reads. So I am confused what went wrong.
I'll realy appreaciate it if you could give me a hint.
