Hi,
I have the following code in assembly(using MARS):

.text
li $v0,9
li $a0,40
syscall

li $v0,9
li $a0,-40
syscall

I'm getting the following error:
Runtime exception at 0x00400014: request (-40) is negative heap amount (syscall 9)

how can i free the heap
thank you

What I have tried:

I've search and all i can find is to use the negative for deallocate. but it didn't seems to work.
