I'm still using the old gcc with sane CFLAGS:
[EMAIL PROTECTED] ~ $ gcc --version
gcc (GCC) 3.4.6 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9)
[EMAIL PROTECTED] ~ $ grep CFLAG /etc/make.conf
CFLAGS="-march=athlon-xp -O2 -pipe -fomit-frame-pointer"
Looks like -fomit-frame-pointer is stripped in the ebuild anyway. Perhaps
it's an issue with the new GCC?

One torrent I'm sharing is 35G with many files and another is ~7G, so on this
512M box if there is memory trouble it should happen quickly.
