Hi,

sorry, just realized that there's a separate list for bug reports
(originally posted to
http://lists.gnu.org/archive/html/help-gsl/2008-09/msg00003.html)

Consider the attached example code; the last assertion fails. Note that
idx2 == 0, but idx3 == 1.
The reason for that is that gsl_interp_accel_find() checks only for
strictly smaller/bigger values.

(Untested) patch attached.

Thomas
