How do you call dub test causing the issue? Maybe there is a 
difference in the configuration/build type.

Also a side remark. You cannot use the output of dmd when 
colouring is on. Dmd lies because the backticks used for 
colouring are not shown. But without them, regex search is 
failing.

I also wonder whether dub Dustmite should be enhanced to search 
for a plain text too. Because while using regex search there 
might be characters which have a regex meaning while user just 
want a simple text search. This could also cause issues.

Kind regards
