simple pthread consumes memory

[balazs]

Hi - I start a simple pthread and the program consumes about 10 Mbytes of
virtual memory. If I start 10 threads, it consumes 100 Mbytes. I don't know
why this is happening to me. I tried it on two Debian and a 64 bit Ubuntu
machines and the same thing happened to me. Thanks in advance for any help.

I compile by:    g++ -lpthread main.cpp

#include <pthread.h>

void* myfunction( void* ptr ) {
        int sum = 0;
        for( int i = 0; i < 2000000000; i++ )
                sum *= i;
}

int main( int argc, char* argv[] ) {
        pthread_t mythread;

        pthread_create( &mythread, 0, &myfunction, NULL );
        pthread_join( mythread, NULL );
}
