It would be interesting to know if slightly modified first version works
too:
   set_with_values(mnzr,(typeof(callback))GSL_FUNCTION(self.f),xn,fn,xLB,fLB,xUB,fUB)

I'm not sure, that it will segfault too. But can't test it on Opteron, sorry
for that.

To clear out the situation, just want to ask, what is the type of callback
variable and how it differs from the type of GSL_FUNCTION(...) expression.
