Forums Bug Reports Stack memory mirc 6.16

Hélo
I admit I don't know what it corresponds to at all but I have this message in my status windows since I have installed mirc6.16:

* Error allocating stack memory (line 105, divers.mrc)

line 105 corresponds to
if (!$2) { return 0 }
and the alias is the next one :

Alias test.list {
if (!$2) { return 0 }
var %test.liste = $chr(47) $+ ( $+ $replace($1,*,\*,.,\.) $+ ) $+ $chr(47) $+ i
if ($regex($2,%test.liste)) { return $regml(1) }
else return 0
}

(I don't know if it's well coded (I guess not...) this alias worked well with other versions ...)
the purpose of the alias is to test if a *!*@host matches with a list of host or 'root of host'
sorry for my bad english I hope you'll understand...
tell me if I've done sth wrong

What parameters are you using when getting the error?

Eamonn.

well this alias is used to detect bad language or bad nicks or hosts in fact :
for instance :
$1 = bite|hitl|mastu|put|queue|salop|sodom|suce|penis|vagin|etalon|chatte|sex|le-pen|le_pen|lepen|sperm|foutre|couille|suck|dick|dominat|batard|cocaine|heroine|zezette|zizi|cochon|petass|chienn|burne|testicul|poitrine|sein|nichon|nibar|porno|anus|rectum|puce (sorry i'm french ^^')
$2 = the sentence pronounced or the nick or the host in other cases ...
Is it due to flood when I have this kind of message ?
(if yes , why did never I got it before ?)
