Hi Brad,
About the GCC bug that sometimes GCC could take gigabytes of RAM (20-75GB) for certain Gambit files,
You mention there that the problem GCC versions are 4.2.* and 4.3.* only, and that "-fno-move-loop-invariants" fixes it.
(I recall that you also reported the issue to the GCC development team and that in response they implemented a "max loops" check internally that fixed it on.. later GCC version, something like this.)
I just wanted to check with you now, that the above was all there has been to GCC's skyrocketing-RAM-consumption issue. So, if I just add CFLAGS="-fno-move-loop-invariants" to my ordinary "./configure --enable-single-host" etc. , no GCC/G++ version will skyrocket?
Are there any more gotchas to GCC use for various versions, except for that "-O2" produces broken code in some particular version?
Thanks!
