bug report

[Ender]

hi,

I've got a bug trying to compile the following function:

//===============================
unsigned long int geraKey(char *name)
{
  union
  {
    unsigned long int key;
    unsigned short int key_short[2];
  };

  key_short[0] = strlen(name);
  key_short[1] = 0;

 /**** THE BUG WAS GENERATED BY THE FOLOWING LINE ****/
  for(int i=0;i<key_short[0];i++)
  {
    key_short[1] += (((unsigned short int) ((unsigned char)name[i])) & 0xff);
  }

  return key;
}
//===============================

the compile options are:

g++ -Wall -lnsl -lpthread -lsocket -fexceptions -o source.cpp -O



to compile the program without errors, I've changed the code to:
(this code is OK)

//===============================
unsigned long int geraKey(char *nome)
{
  unsigned short int n;

  union
  {
    unsigned long int key;
    unsigned short int key_short[2];
  };

  key_short[0] = strlen(nome);
  key_short[1] = 0;

  n = strlen(nome);

  for(int i=0;i<n;i++)
  {
    key_short[1] += (((unsigned short int) ((unsigned char)nome[i])) & 0xff);
  }

  return key;
}
//===============================
