Hi Brad,
About the GCC bug that sometimes GCC could take gigabytes of RAM (20-75GB) for certain Gambit files,

Are there any more gotchas to GCC use for various versions, except for that "-O2" produces broken code in some particular version?
Well, I don't know, I don't follow all gcc development, it seems impossible to answer this question the way it's stated.
If you find a problem I'll look into it.

Ok I'll narrow down my question:
To make Gambit work well (with --enable-single-host) on 4.2.* and 4.3.*, is "-fno-move-loop-invariants" a complete solution?
(The prob AFAIK was that it'd skyrocket to 20-75GB RAM consumption - and "-fno-move-loop-invariants" would bring it down to 1-2GB instead?)
