Some weird server crash issue.

[19:22:54] [debug] Server crashed while executing BF3.amx
[19:22:54] [debug] AMX backtrace:
[19:22:54] [debug] #0 native strcmp () [00406540] from samp-server.exe
[19:22:54] [debug] #1 000444a8 in public OnPlayerText () from BF3.amx
[19:22:54] [debug] System backtrace:
[19:22:55] [debug] #0 004061e4 in ?? () from D:\Program Files\Rockstar Games\GTA San Andreas\03e Server\samp-server.exe

// The snippet:
if(!strcmp(ReturnPVarString(playerid, "ChatText"), text, true)) GivePVarInt(playerid, "CountSpam", 1);

// Stocks:
stock ReturnPVarString(playerid, varname[])
{
    new pvstr[512];
    GetPVarString(playerid, varname, pvstr, sizeof(pvstr));
    return pvstr;
}

stock GivePVarInt(playerid, varname[], int_value) SetPVarInt(playerid, varname, GetPVarInt(playerid, varname)+int_value);

//
Happens if the following string "nösklnagöksagnkö" matches.
Tests in OnGameModeInit shows that it doesn't...
