Some of qemu's code does seem to trigger rather excessive memory

I suspect it's all those large switch statements...
It's on my todo list to report it to GCC, since this memory-hog behavior is
a GCC regression.
We've been working on this in Linaro, and the following two patches
have been posted upstream:
http://gcc.gnu.org/ml/gcc-patches/2011-03/msg00193.html
http://gcc.gnu.org/ml/gcc-patches/2011-03/msg00255.html
so you can probably cross that item off your todo list :-)
