embedding octave - floating point exception

[Marco Driusso]

Running my program under gdb, after some functions that end correctly, I get

Program received signal SIGFPE, Arithmetic exception.
[Switching to Thread 0xb5d176c0 (LWP 15573)]
octave_ieee_init () at lo-ieee.cc:86
86            if (tmp_inf == tmp)
Current language:  auto; currently c++

Have you any idea?
Thanks for the answer!
