My personal recommendation would be to use just about any other snes emulators than zsnes (snes9x, mednafen, higan, retroarch from overlays, many other options) Last official zsnes release is from 2007 and very broken (and a security nightmare), we have many patches to try to resolve this but that has its limits. Your CFLAGS may possibly not help with its dodgy x86 asm use too. There is a fork that I'm considering packaging but it's very recent and hasn't seen much activity yet, also I think it has about the same patches we do -- may possibly not run any better for you.
Yes, I will try others emulators. I already tried the fork from ⁽¹⁾, but it fails on start, not surprising for the moment, let's give them time. I also tried to tweak my CFLAGS without luck (by removing -fstack-protector-strong), but I suppose that this kind of critical flag requires the entire system to be rebuilt. 1. https://github.com/xyproto/zsnes
increasing to critical, because zsnes seems to be unmaintained and totally broken. It should not crash per default unless it is hardmasked. Upstream has several segfault bugs, which remain open since years: https://sourceforge.net/p/zsnes/bugs/166/ and more. There is an interesting fork which is packaged by arch and manjaro: https://github.com/xyproto/zsnes https://repology.org/project/zsnes/versions

Fork also hasn't seen any real activity since its creation (beside readme changes). Now that slyfox is no longer working on this, it may be better to just last rite it but I was waiting to see if the fork started doing more improvements.

I'm under the impression it was working until recently though, given slyfox was still patching it.
I hadn't looked closely at this bug yet, but looks like a continuation of bug #257963
I'm actually not able to reproduce this, although fortify is not properly disabled nonetheless (the fork's explicitly passes FORTIFY_SOURCE=0). Some bits seem messy still, but the fork mostly seem to work. Will probably add it soon.

So this uses current upstream defaults for safety (no libao+debugger, and enable sdl+png+opengl). May possibly have some new issues / regressions to iron out, notably given doesn't use autoconf anymore which shifted many things around. Unsure if this fork will be maintained on the long term, if not then this package may be better off last-rited. bug 817395: fork uses FORTIFY_SOURCE=0 which combined with -U should ensure it's unused even if our gcc enables it by default (issue does exist still, was able to reproduce if letting it use it) bug 829785: cause is unknown but can't reproduce when using the fork Closes: https://bugs.gentoo.org/817395 Closes: https://bugs.gentoo.org/829785 Signed-off-by: Ionen Wolkens <ionen@gentoo.org> games-emulation/zsnes/Manifest | 1 + .../zsnes/files/zsnes-2.0.9-cc-quotes.patch | 8 +++ .../zsnes/files/zsnes-2.0.9-gentoo-zlib.patch | 12 +++++ games-emulation/zsnes/zsnes-2.0.9.ebuild | 62 ++++++++++++++++++++++ 4 files changed, 83 insertions(+)
