I have the same errors with the test data set
miniasm/miniasm -f reads.fq reads.paf.gz > reads.gfa
[M::main] ===> Step 1: reading read mappings <===
Segmentation fault (core dumped)

from miniasm.

Hello
I am having a similar issue.
I was mapping data with minimap (0.2.r124.dirty) and tried next to assemble.
The mapping file size is 457 GB and the machine has > 500GB RAM.
Using miniasm (0.2.r137.dirty) it gives a segmentation fault in step 1.
I updated miniasm (0.2.r159.dirty) but still got the same core dump.
This time I monitored as well closely the RAM consumption and it did not exceed 50% of the RAM
at crush-time.

Hi
No real fix but work-around which was acceptable in my case:

miniasm -Rc2 -f MyReads.fastq.gz MyAlignments.paf.gz > MyAssembly.gfa

This filters contained reads first, which reduced the RAM usage a lot - takes a moment though.
