segfault on archived games #1205
Description
Hi, when I try to start a .cdi in a zip archive, the core crashes.
From the logs:
[libretro INFO] shell/libretro/libretro.cpp:2075 N[BOOT]: retro_load_game: /mnt/df0/data/games/dreamcast/gianas_return/gr-v110b-dc.cdi.zip#gr-v110b-dc.cdi

If I extract the game, it works without crashing.
In case the issue is game-specific; it can be downloaded from https://www.gianas-return.de/?page_id=453 (direct link: https://www.retroguru.com/gianas-return/gianas-return-v.latest-dreamcast-cdi.zip)
While the workaround is obvious, I would really prefer to keep the cdi file in the zip archive.
Main reason: the cdi file is over 700Mb, the archived file (without any particular settings) is under 10MB(!)
In case it's relevant: in retroarch, when selecting the archive, I press on "Browse Archive" and then the .cdi file. After selecting the cdi file, retroarch crashes.
