you are not allocating any memory for *path (it's just a pointer), where the 
strncpy could copy anythinkg to.

void GetPath (char* string, char* result)
{
    char *path;

    strcpy(result, string);
    path=strrchr(result, '/');
    if (path==NULL)
        result[0]=0;
    else
        *(path+1)=0;
}
