Oops - I read the builddlogs in the wrong order. The most recent one
did indeed fail due to an ICE. However, the previous attempt did not
fail with an ICE, and it appears to have used the same version of gcc
(gcc-4.4 4.4.6-6). The ICE'd build also had gcc-4.6 installed, but
gcc-4.4 was still the default.
My successful build was on a system w/ gcc-4.4 as the default, but w/o
gcc-4.6 installed. Today I did a couple new builds - one with gcc-4.6
as the default w/ gcc-4.4 installed, and one with gcc-4.6 installed
and gcc-4.4 removed. Both succeeded.
It looks like gcc-defaults has been updated on the buildds, so I'd
still suggest a retry.
I'm hesitant to do a hand upload w/o the approval of the release team,
but if they'd like to proceed I can certainly do it.
