It actually isn't a bug.

dmd does not bother to keep track of memory for the purpose of freeing it. It 
behaves as if there's a garbage collector.

There is a garbage collector for dmd, but it is left out of the build because it 
slows the compiler down more than it helps.

Excessive memory consumption has turned out to be a problem for the CTFE 
implementation, however.
