hisat2-build failed for Segmentation fault

[yqlan]

I run hisat2-build for a yeast genome using the following command line:

hisat2-build $ref_dir/sacCer3.genome.fa ./ref_idx/sacCer3.genome

it failed with the following message:
"Settings:

the genome size is 12M, and I used 50G memory

I'll appreciate if anyone can help. Thanks.
