Loading Save States Crashes Emulator

I've noticed that in this recent v0.152, that loading save states crashes a lot of games. Example: 2020 Super Baseball.
Win XP 32-bit

Could you please list some more games? Are they all neogeo games?

You might want to open a report at mametesters, including a stack trace.
This is what I get.

Very strange, I tested savestates in the MESS aes driver just last night and they worked fine, but loading a savestate in any MAME neogeo game crashes MAME unless you load the state in the same session as you saved it.

Yeah it works in MAME if you save and load it straight away, but not if you save, exit, start again and then load it. I didn't try MESS.
(even if you save state a, exit, start again, save state b, you can load state b but not state a).
My initial guess is that something in the save state is storing the contents of a pointer and not what it's pointing to, which changes each time you load.

No, it was even more pedestrian: passing the wrong size to save_pointer(). The fact that it didn't crash on MESS when I tested it was sheer dumb luck.

Was this reported to MAME Testers?...(I couldn't register.) Or is this major issue just going to be ignored in favor of working on some new, exciting mechanical slot machines.
(last part was just a joke... relax sycophants)

Yeah, note threads above. Also, you don't have to be registered to view reports at MAMEtesters.
