$ chromium chromium-browser: symbol lookup error: chromium-browser: undefined symbol: _ZN2v82V818AddMessageListenerEPFvNS_6HandleINS_7MessageEEENS1_INS_5ValueEEEE Downgrading v8 to 3.16.14.2 fixes it. Rebuilding chromium against the new version probably fixes it as well, but I don't have the time to verify that now.

I confirm that rebuilding Chromium helps.
Most people aren't hitting this because of fortuitous timing on a chromium upgrade. But if, for any reason, you upgrade v8 from 3.16.14.2 to 3.16.14.9 without immediately rebuilding/upgrading chromium, you'll hit this bug. Bumping the subslot for .9 or making the subslots just match the full $PV should take care of this.
Looks like the symbol change happened in v8-3.16.14.4[1]. I'm going to use that as the soname and subslot. I'll also have to start checking this more carefully I guess. [1] http://upstream-tracker.org/versions/v8.html

Upstream is clearly becoming more crazy - let's make the subslot all parts of the version number.
+ 22 Mar 2013; Mike Gilbert <floppym@gentoo.org> v8-3.16.14.9-r1.ebuild: + Just set soname to ${PV} instead. Bug 462618. Should probably wait for a version bump to do the other branches.
27 Mar 2013; Pawel Hajdan jr -v8-3.17.6.ebuild, +v8-3.17.15.3.ebuild: Dev channel bump. Set SONAME to PV (bug #462618 by Piotr Mitas). Remove old.
