Hi,

The current version works fine.

But it produces lots of debug messages, such as :

-->[x_opt, status, eval_func] = cobyla(x0, test_1, nb_constr_test_1, rhobeg, rhoend, 
message_in, eval_func_max)
DEBUG: lhs = 3 rhs = 1 stack_pos = 8 size_x = 2, size_constr = 0
DEBUG: f = 41.000000, tmp_val = 
68730204254013693000000000000000000000000000000000000000000000000000000000000000000000000000
00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
000000000000000000000000000000000000000000000000000000000000000000000000000000000.000000 
size_x = 2, sizeconstr = 0
etc....

even if the message_in flag is set to 0.

I submit a bug report: http://forge.scilab.org/index.php/p/scicobyla/issues/312/

Best regards,

Michaël
