#558 CPU Exception plus others

[Russell Wiley]

2 part error. All that has been done was install using "sudo apt-get install dosemu"

OS: Don't laugh, I know it's backwards from what most people do. :)
Win10 Home 64bit using Ubuntu Linux subsystem

It would be even more helpful if would recompile DOSEMU and repoduce this
bug with "debug on" in compiletime-settings.
