Not Compiling with Profiling

[JonathanILevi]

When compiling Hunt v1.7.7 in my project with profiling enabled, hunt causes a statement is not reachable warning in std.concurrency.

When I suppress that warning I get a runtime assert error in hunt-extra/source/hunt/collection/Radix.d:294, thrown by std.bitmanip.

I am running Linux (NixOS), Dub verison 1.23.0, and Dmd version 2.095.1.

It seems working to add

"dflags": ["-profile", "-profile=gc"],

to dub.json. Not sure what happed for this.

[JonathanILevi]

I was using dub run build=profile, not sure why it is different.
