Let me know when we can compile QEMU with a modest amount of RAM. Last time I tried, on a memory constrained laptop, it took over 1GB of RAM! That's a lot of memory just to compile a single program. By comparison, I can compile a kernel loaded down with heaps of unneeded drivers with less than 200MB of RAM. I suspect this situation will only get worse with future QEMU releases.

Try again with QEMU 1.7 and recent gcc. There has been a known gcc issue triggered by one of the QEMU source files that requires a lot of memory. A workaround went into QEMU a while back using the gcc -fno-gcse flag for that particular source file.

Although I agree with you, requirement of 1 GB RAM is not much in these days, so probably it will never be optimized.
