Managing memory usage at Compile Time with DMD

[wobbles via Digitalmars-d-learn]

So, I'm writing a poker AI bot. The idea was to generate a lookup 
table of all the poker hands using CTFE so runtime can be as 
quick as possible (as the bot has a very small amount of time to 
act).

There are a LOT of calculations though, many millions of 
combinations.

During complation, this is consuming inordinate amounts of 
memory, 16GB+ (which is all the RAM on my machine + some swap 
space).

I'm wondering is there any techniques to freeing some memory used 
by the compiler so it can be reused?
Are malloc and free usable at compile time maybe?

Another possibilty I was looking at was to write a tool that will 
spit out all combinations at runtime, and then import these back 
into the bot at compile time to build a lookup table that way.

Thanks!
