checked out origin/master this morning at 14ec8a9f814e

$ nice ninja -C out/AndroidDebug -j2000 -l20 chrome_public_apk_incremental && out/AndroidDebug/bin
/chrome_public_apk uninstall && out/AndroidDebug/bin/chrome_public_apk install --incremental

It uninstalls and installs fine but on launch it crashes with the following stack:
