i already posted this in the d NG:

I gave beta 3 on my win32 dev machine a try today and noticed

takes noticeably longer to built. observing the process shows 
that beta3 consumes almost 1.5GB of RAM while dmd 2.064 'just' 
uses 1GB.

I am not so familiar with the compiler code and what could be causing this ? can anyone else confirm this ?

Confirmed, it totally debilitates my 1GB RAM computer with 1GB of swap (taking, as you said, about 1.5GB) whereas with 2.064 it wasn't as bad. Unfortunately I need to use 2.065b3 to avoid a bug. Hopefully the reason behind this can be found (and fixed).
