I've been renaming objects and moving things around in a program,
making little changes, then checking. Now I've hit a point
where it compiles without trouble, and it starts up and
shows a control panel, but after it starts it crashes
with this cryptic output:
dist: 1.897218, cos(angle):0.946970, sin(angle): 0.321321
pi, 3.141593 , sin(pi), 0.000000 proposal: 3.796610,4.609615, SQ:

address@hidden does not recognize error: ModelSwarm (instance)
%s does not recognize %s
Aborted (core dumped)
So I read about this gdb thing and run the program in there,
and the backtrace is:

I've stepped through the code step by step and the last piece
of code before the disaster starts is [ObserverSwarm go], but
I can't say more than that.
I could use some gdb pointers, I guess.
