gcc 4.7.2 was installed on builders last week. Unfortunately, it comes with its own set of problems. See bugs 854085, 854103 and 854105. The worst part (which is unfiled at the moment) is that PGO builds OOM on x86.
This is unfortunate because gcc 4.7's release notes specifically call out LTO improvements for Firefox:
"Link time optimization of Firefox now requires 3GB of RAM on a 64-bit system, while over 8GB was needed previously. Linking time has been improved, too. The serial stage of linking Firefox has been sped up by about a factor of 10."
