[M3devel] cm3 is broken

[Rodney M. Bates]

As of a recent pull from modula3-cm3, done around 16:00 CDT, cm3 is going into
runaway recursion trying to report a fault.  This happens immediately upon
running it, before it produces any output.

Here is one cycle of the backtrace:

#1745 0x00007fd9b0b0d935 in _m3_fault (arg=5600) from /usr/local/cm3-uniboot/bin/../lib/libm3core.so.5

So far, I haven't had the patience to keep hitting return until I get to the bottom of it.
