Comment on attachment 256398 [details] build log That's the unmerge/merge log.
@David: Please read the build logs you attach, and read them thoroughly or you tend to miss this kind of template: * Please do not file a Gentoo bug and instead report the above QA * issues directly to the upstream developers of this software. * Homepage: ${HOMEPAGE}
Created attachment 256555 [details] build log Sorry about that ..trying this in another client
Please file upstream http://bugs.icu-project.org/trac/newticket Note that particular line is fun with endian swapping.

Sorry, can't help you here..
Looks as though it is fixed upstream and hasn't trickled down. I could file a bunch of these...got one on x86 stable building gcc 4.4.x the other day. lilo and grub both have this report as well as pulseaudio and pango among others You guys please consider removing the 'file upstream' on these and allow user bug reports and ask maintainers to file upstream. It seems a bit wrong to ask users to report all these upstream. It requires creating an upstream account for each...maintainers should already have one. Not asking you guys to fix them all just open an upstream bug and report them linking back as above.
Created attachment 311469 [details] build log Fixed in icu-49.1.1-r1 Not closing since 4.8.1.1-r1 still has the report and is in tree.
