That doesn't look like assembly to me.
I assume this is your 'decompiling' of the actual assembly instructions.
It means that there either is a fault in the compiler's compilation, or
in your decompilation.  Without information on what the actual assembly
instructions are, it's hard to say which it is.

You should test what the actual output from the code is, to see if it
does what it's supposed to.
