Details:

Hello!
Looks like I found an bugs in bspline.c., GSL 1.12. At least in
*gsl_bspline_alloc*  and *gsl_bspline_deriv_alloc*  there are a lot of 
code like:
//---------------------------
 w->deltar = gsl_vector_alloc (k);
      if (w->deltar == 0)
    {
      free (w->deltal);
      free (w->knots);
      free (w);
//--------------------------
It means that w->deltal was allocated as *gsl_vector*, but deallocated 
as *void** with memory leaks.

*Have a nice day, *
*Dr. Yevgeniy Naumovich
