I got a problem with STL vectors. I haven an array of structures like this:

struct s
{
vector <Sometype *> vect;
[...]
};


During inicialization I try to do a

s.vect=vector<Cromosoma*>::vector(aSize);

When I compile under windows I got no problem but when I try under Linux I get a segmentation fault error.

Why?

Thanks in advance.

I am a little surprised it compiled on either platform as you are stuffing a "Cromosoma*" into an object declared "Sometype *" (unless you were just throwing some stuff in an example). Please show your exact code (enclosed in "code" tags please).

I changed the types to be more legible because code is in spanish ;)

exactly the code is:

struct mensaje
{
	vector <Cromosoma *> individuos;
	bool valido;
};

And the segfault goes in the second line

mensaje mensEntrada;
mensaEntrada.individuos = vector<Cromosoma *>::vector(numMigracion);

What is the definition of "numMigracion"? I am not that much of a C++ guru, your code doesn't make much sense to me. Is numMigracion already a vector<Cromosoma *> populated with data?

Try breaking the code down into as many peices as you can on separate lines and see what line causes the crash.

numMigracion is just an integer. Is just the size of the vector.

I'm sorry, nothing is coming to mind. The only suggestion I can make is to make a minimal program that exhibits the exact same behavior and post it so I can tinker with it. I have never tried the technique you are using so am unfamiliar with it.

However, I have had mysterious crashes before that as I stripped away other code I 'accidentally' found another problem (usually corruption of memory) that, when fixed, cause the first problem to go away. Try to make a 10-15 line program to reproduce the same error, maybe you will find the problem is somewhere else.

Good luck!
