Note that you can alleviate this under Linux by replacing your
/usr/libexec/gcc/i686-pc-linux-gnu/4.5.3/cc1d (adapt as appropriate, do gdc -v
hello.d to see which backend it uses) with a stub that preloads Boehm like so:

LD_PRELOAD="/usr/lib/libgc.so" $(dirname $(realpath $0))/real_cc1d $@

Note that Boehm has to be built with malloc/calloc/free stubs enabled. Doing
this brought my GDC memory usage down by a factor of six. I can make -j5 again!
