Seems to be some sort of toolchain issue, as the ones that funbars is putting out via appveyor seem to work okay.
I was planning to follow up with them once it settles down and figure out what’s up.
I’m having the same problem on the PS VIta version 1.7.7.
Wii port works 100% speed, no problems. Skips pthread and mutex. Experiment similar things for Windows x64: https://ci.appveyor.com/project/funbars/stella/builds/24712177/artifacts (O3 single-thread mingw) https://ci.appveyor.com/project/funbars/stella/builds/24712180/artifacts (O2 single-thread mingw) https://ci.appveyor.com/project/funbars/stella/builds/24712198/artifacts (O0 single-thread mingw)

Same for me on windows 8.1. Stella 2014 seems to work fine though
Do any appveyor test builds work in either Stella help thread? Stella devs won’t fix until I diagnose and submit. I don’t know why it crashes for some, but there’s a lot of people.
I’m assuming it’s something wrong with our toolchain, though I’m not sure how it differs from appveyor…
Does latest buildbot still break? http://buildbot.libretro.com/nightly/windows/x86_64/latest/stella_libretro.dll.zip
Still not working (x86_64). 
It still crashes, but I was able to create a log file, how can I upload it?

Thanks! Corrupted stack??
Upload stella_debug.txt log. Should narrow fault area within retro_load_game.
Oh? How curious. Creating new logger build. Please wait, will take a bit to build.
While I understand the need of hunting a bug like this, I have to go out of my house for an hour at most. As soon as I get back, I’ll try the new build.
Been working on this problem for a week maybe. No hurry. 
Plenty of people here to try. 
edit: Have bad feeling it’s either magic static initializers or Thread Local Storage. But new log will expose problem.

I have “gl” as video driver, tested changing to “glcore” and “d3d11” with the same results.
Do you need more info about drivers and/or other settings in my retroarch config?
99% sure where crashes. 1 more to verify. Then submit to Stella authors.
Video driver, RA config won’t matter. It’s special coding problem.
