error: segmentation fault

this happened because you tried to execute
the address `0x003e0000`, which is not a valid address to execute

the instruction that got us here was:
0x00400000 1   [0x10008000]    beq    $zero, $zero, -32768 #  main:b end


tip: the address `0x003e0000` is not part of any segment
