And finally, it shows me something. I've seen this problem somewhere around here before, I can prolly fix it.

I guess I didn't see it. I saw a reference to it, but it wasn't actually the problem. Here's the code, I can't see what is wrong with it, and I showed it to a friend who dabbles in code, but he's almost as rusty as I am, and he said the same, that it should be working.



{
	BAN_DATA *pban;
	char new_host[MAX_STRING_LENGTH];
	int i;

	for ( i = 0; i < (int) strlen( d->host ) ; i++ )
		new_host[i] = LOWER( d->host[i] );
	new_host[i] = '\0';

	for ( pban = first_ban; pban; pban = pban->next )
	{
		if ( pban->level != LEVEL_SUPREME )
			continue;
		if ( pban->user && str_cmp( d->user, pban->user ) )
			continue;
		if ( pban->prefix && pban->suffix &&
		     strstr( pban->name, new_host ) )
		{
			if ( check_expire( pban ) )
			{
				dispose_ban( pban, BAN_SITE );
				save_banlist( );
				return FALSE;
			}
			else
				return TRUE;
		}
		/*
		 *   Bug of switched checks noticed by Cronel
		 */
		if ( pban->suffix && !str_prefix( pban->name, new_host ) )
		{
			if ( check_expire( pban ) )
			{
				dispose_ban( pban, BAN_SITE );
				save_banlist( );
				return FALSE;
			}
			else
				return TRUE;
		}
		if ( pban->prefix && !str_suffix( pban->name, new_host ) )
		{
			if ( check_expire( pban ) )
			{
				dispose_ban( pban, BAN_SITE );
				save_banlist( );
				return FALSE;
			}
			else
				return TRUE;
		}
		if ( !str_cmp( pban->name, new_host ) )
		{
			if ( check_expire( pban ) )
			{
				dispose_ban( pban, BAN_SITE );
				save_banlist( );
				return FALSE;
			}
			else
				return TRUE;

	}
	return FALSE;

I'm not so sure that line is the actual problem, as it's the same code across all the Smaug codebases. That is where the Seg Fault occurs, but it is not telling us why.

Did the seg fault dump any core files? Check in your main DBSaga dir. If so, try this;
gdb DBsaga core.11231

(change the core file # to whatever you have)

Did that seg fault occur when you tried to connect?

Since it is failing here:


1116 for ( i = 0; i < (int) strlen( d->host ) ; i++ )


... you need to reproduce the crash in gdb, and then get some debugging information out. My page about gdb should help.

For one thing, find out about the variables that have caused the crash, almost certainly d and d->host.

First thing to do is type:


bt


That shows a backtrace, which shows where this code was called from. Then look at the variables:


p d
p d->host

Wierd. I have a "stackdump" file in my areas folder, now. :/ Is this what I am supposed to be looking for? Heh.

You can reproduce it every time, right? So don't muck around with old core files, just run the MUD under gdb the way I described earlier.
