If you get unpredictable segfaults, try setting SWARMHOME!

Subject:	If you get unpredictable segfaults, try setting SWARMHOME!

After Marcus announced yesterday that setting the environment variable
SWARMHOME fixed the crashes of the swarmdemo programs, I've had
segfaults with Swarm code that go away after setting SWARMHOME.

For example, I was trying out Pietro T's bp-ct program, and in the
Makefile I set Swarmhome. but the program segfaulted at run time:
$ ./bp-ct
Segmentation fault (core dumped)
address@hidden bp-0.97-ct-0.17-tmp990613]$ gdb .libs/bp-ct

(gdb) q
The program is running.  Quit anyway (and kill it)? (y or n) y

Strong hint here that that the lack of SWARMHOME in the environment is
the cause, so try:

address@hidden bp-0.97-ct-0.17-tmp990613]$ export SWARMHOME=/usr

Then the program runs.  


I have not installed the most recent snapshot of Swarm, I still have
2.0.1, so this last problem I found may already have been fixed, but I
figured I better grab the backtrace while I had it on the screen.
With Pietro's bp-ct app at least, hitting the "quit" button before start
or next causes nothing to happen, and there is a seg fault if I hit
start after that.
