That's not a crash, is it? The functions inform you that they didn't
converge.

See

d9lgit.f needs an improvement, either directly or by completely
replacing it with something better.

I called it a crash since the functions aborted without returning a  
meaningful value, but it doesn't crash Octave. Calling it a failure  
may therefore be more appropriate.

Thanks for pointing me to this bug report. I hadn't noticed that the  
bug in poisscdf() was indeed caused by the same problem in gammainc(),  
itself caused by a problem in d9lgit.
