Segfault when trying to enter fullscreen.

On latest git, with Glide64 Retroarch crashes when I try to enter fullscreen. (not game specific)

Segmentation fault

I tried to figure it out myself, sorry.

Yeah this happens with Glide64 mk2 right now. It will be fixed before release.

Was this with Glide64mk2 or glide2gl? Because the default Glide64 plugin (glide2gl) doesn't have this problem for me. Glide64mk2 doesn't even build at the moment, so no clue what the status is on that one.
