Has anyone made the task library for a sun successfully? If so, I would
like to hear from them ... I have installed
	- c++ (v 1.2)(minus the task library) successfully on a gould
	- c++ (v 1.2)(minus the task library) successfully (i think) on a 
	  sun-3/50 running release 3.3
However, when I install the task library on the sun and try to run
the example in appendix c of "a set of c++ classes for coroutine style
programming" (part 3 of the release notes), the program dumps core. Output 
is as follows:
	main
	new pc(a,144100,144272)
	Segmentation fault (core dumped)
adb gives the following trace:
	__task_restore
	__sched_schedule
	__task_sleep
	__qhead_get
	__pc_ctor
	_main
I have tried another noddy program, and it results in the same behaviour.
The only modification I made to the example was remove the void declaration
from the constructor (otherwise it wouldn't compile).
