The compile error hints at a problem with the outdated build toolchain on ALARM. If this indeed the case, I'm not sure how difficult it will be to compile Chromium. Regarding the issue with re2: You can can downgrade the package to the last version compatible with chromium (re2 1:20230301-1) and withhold upgrades until the problem is resolved; I don't think there is much harm in skipping upgrades of re2.
