graphmap: segfault when building index only

Hello Ivan,

I was trying to build the index for my simulated GRCH38 genome using the command line:

graphmap align -I -r grch38.simu.fasta

The index ran about 7 minutes before issued seg fault error (see the file attached below).

graphmap.index.err.txt

I also tried to use .fa as the reference extension and with/without reads file, and the error persisted.

I am using graphmap v0.3.2.

Any insights on how I could fix this?

Thanks, Simo
