I hadn't, so I tested it now with current master
(v2.090.0-beta.1-118-g8fc81f40d) and I get the same results. Further I tried a
64-bit compiler (with digger build --model=64), and it runs out of memory too.

I've also retried the bisection several times hoping it would land on a
different commit, but I get the same one. I even made the tester script test
each build three times so as to not miss something due to transient successes.

The only thing that works so far is to copy/paste the build command `dub build
-v` prints and run it with -lowmem added. Curiously dub with -lowmem DFLAGS
does not seem to work. Manually calling dmd with the same command does.
