Hi,
I think it will just hit the same wall (if there is only one (or n*3+1) topic).
This may help a bit:
$i = 0;
while ($list && $list->fetch() {
if ($i++ == 0) { echo "<tr>"; }
?><td align="left" valign="top">
<a href="&(list.id);.html">&(topic.name);
</a></td><?php
if ($i <= $x_in_a_row) { echo "</tr>"; $i = 0; }
}
if ($i > 0) {
for ($j=$i; $j <$x_in_a_row) { echo "<td> </td>"; }
echo "</tr>";
}
Well, the question remains, why $list->fetch() should leads to segfault and not
just return null/0/or_any_thing_else?
