Nightly 3DS build crashes on opening sdmc

[donmor]

Description

I upgraded retroarch on my new3ds to latest nightly build, and every cores cause arm11 panic if I open sdmc.

Expected behavior

Retroarch can browse and load content

Actual behavior

Any attempt to read feom sdmc crashs the Arm11 subsystem. Libretro cores that don't require content can run as usual.

Steps to reproduce the bug

1. Do a fresh upgrade to nightly build
2. open retroarch, load any core, and enter "Load Content" > "sdmc:/"

Bisect Results

This accurs after I upgraded retroarch and its cores to nightly from a quite old version, with everything under /retroarch purged.

crash_dump_00000001.dmp
I dumped this when it crashed.

One more thing, browsing sdmc:/ from Settings > Directory > (any entry) won't crash the machine. Using playlist can also avoid crashing and load contents.

Could you try an older nightly for me? From before my commit 790deeb which was yesterday my local time.

I'd try it out later.
