Hi Heng!

It's been some time, but I'm back with a SEGFAULT that I'm getting for some low-complexity reads and was able to reproduce it on the command line with vanilla mm2.

./minimap2 --lj-min-ratio 0.1 -k 19 -H -a ref.fasta qry.fasta

https://github.com/lh3/minimap2/blob/master/align.c#L747
r->p is a nullptr.

fasta.zip

Thanks,
Armin
