dub dustmite: Initial test fails

[denizzzka via Digitalmars-d-learn]

Hi!

I have a code with segfault. I decided to try to take advantage 
with dub dustmite:

$ dub dustmite ~/ssd/pgator_dustmite0 --program-status=139 -- 
--config=my_pgator.conf --debug=true

but if I try to run already compiled binary it is successfully 
core dumps:

How how to understand why dub dustmite doesn't work for me?
