JE rel8 jumps to the wrong location #120

Closed DarrenStahl closed 11 years ago

DarrenStahl commented 11 years ago

Steps to reproduce:

  1. Load lab41b.OBJ (provided by email)
  2. Step through program
  3. Observe the JE after printing the string jumps the IP to 0x0025 rather than 0x1025

Notes: Looking at the addresses it seems rather obvious that the top byte of the IP is being ignored in rel8 jumps. Should be an easy fix.
