Crash when using JIT

[Rustrain]

ppsspp crashes every time when I start a game, after the loading screen flashed. Everything is normal until I rebooted my phone just now,though. I tried to fix it by adjusting the configs and installing earlier versions, but that doesn't help. Finally I discovered that when using interpreter mode the games can be started, but is very slow(possibly 100x slower),and is impossible to play.
Is it a bug or something? How can I fix it?(This bug was also triggered before, when I was saving states)
ps I'm using Huawei P7 and was playing Sora no Kiseki SC.
