Dashmips raises exception at running the following code

[dcordb]

The following code runs perfectly using SPIM emulator version 8.0:

.data
	abort: .word	object_abort

.text
	object_abort:
		jr $ra

	main:
		li $v0, 10
		syscall

Yet dashmips fails to execute it, giving the following exception:

Traceback (most recent call last):

I'm using python 3.8.5 and dashmips 0.1.10. Which specification of MIPS does dashmips support? I couldn't find this info anywhere.
