Also, adding GC.collect() and GC.minimize() explicitly did nothing as well.

If you take out iota as well, it works again.

If you add a sleep into the while, the memory increases more gradually.

FWIW, I can't reproduce it on x86_64 Linux with DMD master. I've even raised the multiplier up to 128000, and RES stayed at a modest 19MB.

The initial test was on:
  DMD64 D Compiler v2.066.1

I just tested it on (dmd master):
  DMD v2.067-devel-8ff302a DEBUG

It takes up insane amounts of memory on both. (only tested on mac)

AFAIK the heap on OSX starts 0x 0x1_0000_0000, so your "b" members create false pointers into the memory chunks into the arrays allocated in the while(true) loop. That's why they are never collected.

You might want to try one of the proposed precise GCs: https://github.com/D-Programming-Language/druntime/pull/1022 or https://github.com/D-Programming-Language/druntime/pull/1057
