core crashes; reproducible; stack trace included

[AlexFolland]

To cause this crash, I played the story mode of The Last Blade - Beyond the Destiny (Europe) until I defeated Shinnosuke Kagami using Yuki. After I defeat him, the game crashes. @fr500 told me to reproduce it with Dr. MinGW installed so I could get a stack trace easily. I did so. Here it is.

I have hunch this was the same bug as #22.

core_serialize calls retro_serialize, which is where the other bug was.

https://github.com/libretro/RetroArch/blob/709c7de40fdcab0d968d454e6aa2c2614bd5799e/core_impl.c#L318-L323

This is a runahead bug fixed in the frontend? Or the core still has this crash problem?
