[m-dev.] Open bugs causing compiler aborts

[Julien Fischer]

Hi all,

The following bugs regarding compiler aborts are all currently still
open.  It would be good to try and get these fixed where practical. (I
am aware that in same cases the "fix" is "implement a new mode
analyser", but ...)

I have a proposed fix for #184 lying about.

#278 is just matter of working out what an appropriate error message to
emit is.  (Prior to Zoltan's rewrite of the state variable
transformation it would have been a mode error.)

I think the tabling related ones are due to bits of tabling
infrastructure being left over after dead procedure elimination has
eliminated the tabled procedure.

Cheers,
Julien.
