icu 4.8.1 previously built fine in rawhide in the mass rebuild it failed in the tests with quite a number of test failures.
The previous build on December 13th built OK so its possibly a regression in gcc
I've tested the build up to and including gcc-4.7.0-0.8.fc17
assigning to gcc as likely a gcc issue
That needs analysis by the package maintainer first. It might be a GCC issue, but it might also be (and more probably) just package bug, strict aliasing violation, undefined behavior code etc.
If you suspect a gcc bug, it needs to be first reduced into a small self-contained reproducer. Thanks.

@pbrobinson: I noticed you updated the ICU to version 188.8.131.52, did this package actually build with other gcc versions?

Scratch build on f16 builds fine
This turned to be a GCC bug, icu/source/test/cintltst/cbiditst.c u16ToPseudo function is miscompiled. But next time I'd really appreciate if at least the binary search (if doing brute force search) would be done by package maintainers who know their code better than me.
