I guess it doesn't because dub probably uses a response file containing all cmdline options, whereas -lowmem definitely [and --DRT-* probably] need to be direct cmdline args. Is this something I can/should report? (Where do dub issues go?) Replying here despite the delay because this is one of the top post when one google for gcopts. This will be possible with the new version of the runtime (>=2.091.0, not released yet). It has been filled as https://issues.dlang.org/show_bug.cgi?id=20459 and was fixed in https://github.com/dlang/druntime/pull/2881 which means dub compiled with druntime >= 2.091 will allow you to do: `dub -- --DRT-gcopt=profile:1` And any other D program will ignore `--DRT` options if provided after the `--` delimiter.

See example here https://dlang.org/changelog/2.085.0.html#gc_cleanup I need it to apply to dmd though, I'm exceeding memory limits when compiling. Once done the program doesn't need a whole lot of it, but dmd -lowmem does.
