Hi,

I'm trying gambit 4.6.4 under Ubuntu 32bits, 64 bits and Gentoo 64 bits. It compiles fine in these systems. However:

- Ubuntu 32 bits: fails to compile blackhole, with an out of memory error
- Ubuntu 64 bits: compiles, but on a 16gb ram machine.
- Gentoo 64 bits: uses all 4gb of ram and takes forever using swap. I didn't finish compiling, because taking that long makes it impossible to develop Blackhole.

I've read in the git commits that now the default flag is -O2, could this be the reason?

Best regards

Álvaro
