Segmentation fault in lr-mame2016 for rtype2

[bollwerk]

Pi 4b, RetroPie 4.6.5
rtype2.zip (part of a clean 0.174 set, verified with clrmamepro)
lr-mame2016

Any ideas why I would get this message on a rom that should be validated and working?

I'm not sure what to make of this error, or what to do, other than try another core/emulator with a different version of the rom.
But this rom SHOULD be working, as it passed validation with clrmamepro and is listed as "good" in this version of MAME.

@bollwerk I tried it now and sometimes the game loads, sometimes it doesn't, and sometimes it works without the menu screens. Weird. I am using an experimental kernel and the kms video driver so there might be bugs with that.

Here's a verbose log: https://pastebin.com/25ZvhUBh

Seems to work fine on fb-neo.
