cool!

Could you please also collapse it into just a single macro? The 
ENTRY/END sequence can be generated by the macro. (if you do it then 
please do it in a followup patch, i'll look at and apply your current 
series)

Something like:

  PARANOID_ERROR_ENTRY(stack_segment)

Could do all the magic, right?
