--DRT flags are for run time, not compile time. They're intended 
to be passed to your executable and not the compiler. From the 
docs [1]:

"By default, GC options can only be passed on the command line of 
the program to run"

With dub, anything following a solitary -- on the command line 
will be passed to the application [2], so you probably want 
something like this:

dub test -- --DRT-gcopt=profile:1
