Testing against 1.8.5 is as simple as changing this line in src_configure(): $(if use hppa || use ia64 || use mips; then echo --with-mozjs=mozjs185; else echo --with-mozjs=mozjs-17.0; fi) ...to just --with-mozjs=mozjs185 ... As for the error itself, the change to the way context and memory works in mozjs-17 vs mozjs-1.8.5 is definitely complicated enough that polkit might be triggering issues as per what is alluded to in the freedesktop bug. IIRC there's a reason why the spidermonkey-17 dep forces off the debug flag, and technically anything using spidermonkey should still be fine despite all of the asserts that get inserted with USE="debug" but polkit isn't (again, iirc).
Yeah, it looks to work ok with the older mozjs I will probably make a revbump to use that version, that will also allow to kill :17 slot as this was the only reverse dep (this is exactly what Debian people did long time ago too with polkit vs. mozjs)
0.113 uses mozjs-185
ok this is indeed related to freedesktop report and the fix is in 113 version, however this has nothing about restriction of spidermonkey dependency. This leading to https://bugs.gentoo.org/show_bug.cgi?id=554836
I am reopening this issue on behalf of angry_vincent on IRC. The upstream bug says the problem should be gone in 0.113 but the ebuild still uses the 0 slot. Shouldn't we modify older ebuild to use slot 0 and use slot 17 in 0.113 release ?

Personally I would prefer to still use spidermonkey-1.8.5 that is the one used by Debian. Also, the only consumer of spidermonkey:17 slot was polkit (while a lot of other things are still relying on 1.8.5). This also avoids to having spidermonkey:17 being used in a few arches and 1.8.5 on the rest for the same polkit version
We discussed this a bit more with pacho yesterday and I think that we agree that if spidermonkey is only used for polkit, then we might as well remove it from tree with pacho's argument about support of 1.8.5.
CLosing then :)

(In reply to Pacho Ramos from comment #7) > Personally I would prefer to still use spidermonkey-1.8.5 that is the one > used by Debian. But it's not used by polkit on Debian, as far as I can gather: https://lists.freedesktop.org/archives/polkit-devel/2015-September/000465.html (The same discussion shows that they considered moving to Duktape, attempting to port to a newer mozjs or abandoning JavaScript rules entirely. But it's been a while since that discussion, too...) Also, spidermonkey-17 is what is used on recent versions of openSUSE: https://build.opensuse.org/package/view_file/openSUSE:Factory/polkit/polkit.spec?expand=1 (line 59) > This also avoids to having spidermonkey:17 being used in a few arches and > 1.8.5 on the rest for the same polkit version But spidermonkey-1.8.5 doesn't build on x32 at the moment (bug #439558), whereas spidermonkey-17 builds fine. And this particular issue seems to indeed have been fixed in 0.113, since I don't get those kernel traps on my machine. Why not have a USE flag to toggle it, then?
We are not going to revert back to use another completely dead spidermonkey version. At least now we can mostly rely in only 185 version and 24, but we don't need to also start randomly trying to support all the broken spidermonkey supports relying on completely dead versions. The way to go is to kill any spidermonkey requirement, but polkit upstream has still not done that
