Crash when emulating mips in 2.1.3

[peace-maker]

This crashes unicorn 2.1.3 and was fine before:

# from pwnlib.asm import asm
# code = asm('''
# move $t9, $gp
# move $t7, $ra
# jalr $t9
# addiu $t8, $zero, 0x10
# ''', arch='mips', endian='little')
code = b'%\xc8\x80\x03%x\xe0\x03\t\xf8 \x03\x10\x00\x18$'

import unicorn
address = 0x1000
uc = unicorn.Uc(unicorn.UC_ARCH_MIPS, unicorn.UC_MODE_32)

uc.mem_map(address, 0x1000)
uc.mem_write(address, code)

ctx = uc.context_save()
for i, pc in enumerate(range(address, address + len(code), 4)):
    uc.context_restore(ctx)
    try:
        uc.emu_start(pc, until=-1, count=5)
    except unicorn.UcError as error:
        print(error)

pwntools CI crashed due to this.

Your observation is correct.
