Can you show emerge --info dev-libs/libxml2?

Sorry, and what version of dev-libs/icu too?

This seems really strange. Did you manage to work around it, given you reported bug 949854, or did it only affect 25.2.0 and 24.8.4 was fine?

Hello Sam,

I also met this issue with 25.2.0, however 24.8.4 seams fine as far I used it.

I didn’t update icu as you can notice, it’s usually a big upgrade before of all the reverse dependencies, I might upgrade a bit later.
