For my case when linking a bunch of object files (when generating a shared
library), it takes less than 10 seconds with g++-4.0 vs 15 minutes for
g++-4.1. I am not starved for memory in either case.
Unfortunately, the application is very large (lots of c++ files) and I am not
sure how I would need to proceed to actually par this problem down so it can
be examined by someone more knowledgeable than me.
