Will be fixed in 5.2: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65801
(In reply to octoploid from comment #1) > Will be fixed in 5.2: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65801 Will there be a 5.9999 ebuild (since it might take some time for 5.2 beeing released) ?

I don't know. But it might be a good idea to add the patch to 5.1.

In addtion, I have patched gcc-5.1.0, see https://bugs.gentoo.org/show_bug.cgi?id=548412 With this patch and the proposed work-around here, I could emerge chromium-44.0.2383.0 without any problems.
The "fix" of casting to unsigned char is pretty ugly. I think we will just wait for the next gcc release unless chromium upstream applies some fix. The patch below seems to do the job. https://gcc.gnu.org/viewcvs/gcc/branches/gcc-5-branch/gcc/cp/typeck2.c?view=patch&r1=222636&r2=222635&pathrev=222636

(In reply to octoploid from comment #7) Thanks for the info.

Created attachment 403616 [details, diff] chromium-42.0.2311.135-gcc-5.1.patch For those experimenting with gcc 5.1: The proposed work around patch from comment 4 of upstream bug 466760 backported to apply to the stable www-client/chromium-42.0.2311.13, to apply, save the patch to this directory: mkdir -p /etc/portage/patches/www-client/chromium-42.0.2311.135 For later chromium versions, try the earlier patch (02432: proposed work around patch from comment 4 of upstream bug 466760),something like (depending on the chromium version): mkdir -p /etc/portage/patches/www-client/chromium-43.0.2357.18 cp chromium-44.0.2384.0-gcc-5.1.patch /etc/portage/patches/www-client/chromium-43.0.2357.18
(In reply to Mark Wright from comment #10) I would suggest patching gcc instead. gcc-5.2 will have a fix for this.
This should really be fixed in Chromium. The code violates the stricter narrowing rules in the C++-11 standard. Our policy is to always prefer fixing the code over adding flags that relax standard conformance (eg. -fpermissive). By the time we unmask GCC 5 this will probably be have been fixed in both places so it doesn't really matter in this case.
*** Bug 552550 has been marked as a duplicate of this bug. ***
(In reply to Ryan Hill from comment #12) Sure. I a patch gets accepted by chromium upstream to fix the code, I certainly have no objection to it!
I forgot we also have bug #550852, so we do need to fix something GCC-side. :D
This should be fixed with gcc-5.2.0.
