Build: kodi libretro, MGBA v0.8.4

Whenever I leave a game in kodi, kodi crashes with a segfault within game.libretro.mgba.so

Sorry for providing limited additional information. The crash occurs on a raspberry pi 3, using OSMC media center. MGBA addon has been installed as a regular addon in kodi 18. If you could explain where/how to get a debug build of game.libretro.mgba.so, I would be happy to provide more detailed information about the crash. The crash seems to occur independently of the game that is used. I tried with Super Mario Land and Zelda, resulting in the same 100% reproducible call stack

I don't seem to be able to reproduce this with a debug build on regular Android RetroArch, and I'm not sure how Kodi builds their mGBA core.
