Yup, I'll attach that in a moment. I also have the 'genrecog.s' file, if needed. I'll also add that it takes the command about 20-25mins to fail, which is very abnormal. This machine might be old, but the CPUs are 600MHz, and they can still chew through some of the largest C/C++ source files in under a minute in most cases. So it seems like something in the stage2-bubble xgcc/xg++ gets stuck in a loop and consumes additional memory with each iteration until it hits some kind of boundary and bails.
