Follow-up Comment #5, bug #30754 (project octave):
you are right. it seems that the issue is either in interfacing to GSL, or in
GSL itself. if I use legendre (octave function) instead of legendre_Plm (GSL
function), then octave doesn't crash.
however, it has a huge performance drawback in my calculation, since legendre
evaluates for all m=0:n while legendre_Plm only evaluates P(n,m), and I need
only m=1 for large n.
