ICU 58.1 works fine for me, except with the Mozilla family of products. For thunderbird and Firefox it's enough to disable with-system-icu, after that the segfaults go away. Other programs which depend on ICU work fine with the new version. I've tested Chromium 54, Evince and Libreoffice and all are stable so far. But I don't see problems with downgrading ICU either.
