Alexandr Druzhinin:
32 bit versions (using dmd and gdc, win7/ubuntu 12.04) of my
application always leak very fast. But 64 bit version (ubuntu 12.04
only, win7 segfaults) works stable without any leaks. I'm curious is
there some workaround or I have to wait for GC improvement to build
32bit version, without choice?
This difference is caused by the difference in pointer space size
coupled with the nature of a conservative GC.
The "workarounds" are not easy, like allocating your largest arrays from
the C heap.
The past Summer Of Code was worked on a much more precise GC (but not
fully precise) meant to reduce this problem a lot on 32 bit systems, but
nothing solid has so far come out of that. It probably needs to be
polished, tested, etc.

Thats not correct. Rainer Schuetze has finished it and is using it for
VisualD. You can get a version of druntime which the percise GC from his
github branch https://github.com/rainers/dmd
