Bug: free_shellcommands is not unlinking entries from the list
Discovered in: AFKMud 1.64
Danger: Low - Only applicable during shutdown or reboot
Found by: Samson
Fixed by: Samson

In shell.c, locate:

void free_shellcommands( void )
{
   SHELLCMD *scommand, *scmd_next;

   for( scommand = first_shellcmd; scommand; scommand = scmd_next )
   {
      scmd_next = scommand->next;
      free_shellcommand( scommand );
   }
   return;
}


Replace with:

void free_shellcommands( void )
{
   SHELLCMD *scommand, *scmd_next;

   for( scommand = first_shellcmd; scommand; scommand = scmd_next )
   {
      scmd_next = scommand->next;

      UNLINK( scommand, first_shellcmd, last_shellcmd, next, prev );
      free_shellcommand( scommand );
   }
   return;
}


Ordinarily such a bug would be a bad thing since it's a memory leak. However since free_shellcommands is only called by cleanup_memory this results in nothing more than a potential annoyance during shutdowns and reboots. Valgrind users may get warnings about lost blocks during debugging.
