I write part of the valdgrind message when I execute my
program. I don't understand anything. What can I do? 

==1166== Use of uninitialised value of size 8
==1166==    at 0x8060D1C:
OperIteracion::hallarPrototipoNoVaso(perfil *, int)
(OperIteracion.cpp:43)

==1166==    by 0x80671F4: Tracking::hallarPerfil(Image *, p,
Perfil *, int, int) (Tracking.cpp:478)

On the other hand, if I use gdb, I receive the following error:

Program received signal SIGSEGV, Segmentation fault.
0x400fcbf3 in mallopt () from /lib/libc.so.6
(gdb) 

I hope your help. Thanks!
