Hey, I haven't tried mupen64, but I'm one of the SDL developers, and we're trying to get a reproduction case for this issue. Can anyone seeing this get a backtrace...

I hate to bump an old github issue, but by any chance was there ever any progress on this? I'm moving ancient buildbots from 0.8.9 to 2.7.0, and was surprised...
