Eliot, all,
My GSL code, with callbacks is confusing me. First, I call gsl_multifit_fdfsolver_set(). This seems to work, hitting various callbacks (apparently successfully), but then gives an error with #'bad number of arguments'. I have looked, and don't see an invalid
number of arguments anywhere. I can proceed past that(??), only to crash in gsl_multiroot_fdfsolver_iterate().
The C backtrace appears below. Is there anything I might glean from it? Any ideas?
Bill
