Proposed patch

Hi mtest1,

  Ah - yes - I know why I could not reproduce this problem now ...  There is
  a long standing problem with Fedora which makes it impossible to build
  32-bit binaries with address sanitization enabled.  So my i386-elf toolchain
  actually has 64-bit executables in it rather than 32-bit ones.

  Please could you try out the uploaded patch and let me know if it resolves
  the problem ?  It may not work however as all it does is to (try to) stop 
  the illegal memory access inside i386_intel_simplify_register().  It does
  not address the underlying problem of why an illegal register number was
  being used in the first place.

Cheers
  Nick
