While updating webkit-gtk it just failed with the following:

I can confirm this bug.

I can confirm as well this bug.
Comment 3 Albert W. Hopkins 2016-03-07 14:59:17 UTC
Does anyone know of a work-around for this issue?  It seems that this issue prevents gnome/stable updates from finishing and masking this version fails because dependencies are not met.
Comment 4 Pacho Ramos gentoo-dev 2016-03-09 15:23:04 UTC
I cannot reproduce this

Also, I see you both are using -Os CFLAG... can you try only with -O2? (also, I see that in one case you are specifying -O2 and -Os at the same time... that doesn't make much sense to me, -Os is like -O2 without the options that will increase the size)

... a bit late responding to this:

Yeah, for me changing C(XX)FLAGS to "-O2" works for me.  I sometimes forget I have "-Os" (this is for a virtual machine build) and so I forget to first try "-O2" and it's been a while since "-Os" presented any problems for me.  webkit-gtk finally build with that C(XX)FLAGS change and I'll just put that in /etc/portage/env.
Comment 6 sf 2016-03-10 13:30:07 UTC
Adding -O2 fixed the problem for me, as well. Thanks.
Comment 7 Johannes Buchner 2016-03-11 18:45:37 UTC
I reported this upstream at https://bugs.webkit.org/show_bug.cgi?id=155371

Moving to -O2 is a workaround but not a solution (as setting this affects all packages).

I wasn't able to compile webkit-gtk-2.10.7 with -Os with gcc 4.9.3, but when I upgraded gcc to 5.3.0 it compiled with -Os.
Comment 9 Brendan Jurd 2016-06-27 08:03:09 UTC
I can confirm that this build fail is still present with net-libs/webkit-gtk-2.10.9 versus gcc-4.9.3 (both latest "stable" for amd64 at time of writing).

Changing -Os to -O2 in CXXFLAGS seems to be working around it for me as well.

Upstream produces now a patch.
Comment 12 Pacho Ramos gentoo-dev 2017-01-21 12:14:44 UTC
What is the status of this with 2.14.x? It seems upstream considers it solved... but per some reports in upstream bug report... maybe it's still happening in some situations :/
Comment 13 Alexandr Tiurin 2017-04-07 22:38:24 UTC
I confirm

Comment 15 Mart Raudsepp gentoo-dev 2018-02-23 06:13:03 UTC
Is this still an issue with webkit-gtk-2.18.6 (or newer if looking later)?
Comment 16 Walther 2018-04-02 23:44:26 UTC
webkit-gtk-2.18.6 compiles now fine in my system. Most likely because the currently stable gcc version is now 6.4.0, so this bug shouldn't be hitting stable users anymore.
Comment 17 Mart Raudsepp gentoo-dev 2018-04-14 19:24:07 UTC
Lets call this obsolete then (especially with icu + 17.0 profiles). Glad it's working now.
