Setting the jit USE flag seems to prevent this bug.
(In reply to Myckel Habets from comment #2) > Setting the jit USE flag seems to prevent this bug. You should not enable JIT on a hardened system because any process using webkit-gtk will be killed by a pax hardened kernel with an rwx mmap. Interestingly enough, this is an i686 bug. I was not able to hit it on amd64.
Created attachment 367766 [details, diff] Patch for upstream bug #112141
Created attachment 367768 [details, diff] Patch for webkit-gtk-2.0.4.ebuild
A discussion of this compile error on 32-bit arches can be found upstream at https://bugs.webkit.org/show_bug.cgi?id=112141 and there is a related chageset at http://trac.webkit.org/changeset/145551 In the attachments you will find a patch based on changeset 145551 and a patch for the ebuild. Since I am not a gentoo developer these should be scrutinized by the powers that be. The patch based on this changeset was tested on both ~x86 hardened and ~amd64 hardened and the ebuild built without errors and browsers based on webkit-gtk-2.0.4 (midori, epiphany) worked without problems when taking the acidtests at http://www.acidtests.org .
Sorry for the noise, but only epiphany is currently using webkit-gtk:3 (and thus webkit-gtk-2.0.4), midori on my systems is still using webkit-gtk:2 . So the tests with midori are not relevant in this context.
Should be fixed in 2.2.4 and 2.2.4-r200
confirmed that this work on both ~x86 and ~amd64 with or without the jit USE flag.
