GC, memory leaks and 32/64 bit

[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?
