<div class="moz-cite-prefix">Hi all,<br>
<br>
We had to temporarly fix this problem as we have to go in
production. The problem is in
osg::Text::computeAverageGlyphWidthAndHeight() line 602:<br>
<br>
for (i = 0; i < _coords->size(); i += 4)<br>
<br>
sometime it happens that _coords->size() is not multiple of 4
leading to an out of range access to the _coords array. To avoid
the crash I fixed this way:<br>
<br>
unsigned int sz = _coords->size() - (_coords->size() %
4);<br>
<br>
for (i = 0; i < sz; i += 4)<br>
{<br>
...<br>
} <br>
<br>
Of course this need to be fixed in some other way as it avoid the
crash but probably do not give the correct result.<br>
<br>
Best Regards,<br>
<br>

Hi Robert,
<div><br>
</div>
<div>I’ve not tried other OS combinations yet but I made that
simple test in the osgtext sample too and the crash happens.</div>
<div><br>
</div>
<div>I’ll see if I can reproduce it on OSX.<br>
<br>
Thank you.</div>

<div>Have you tried any other OSG+OS combinations? Is
so they exhibit the problem?</div>
<div><br>
</div>
<div>FYI, there are so major internal changes to
osgText since 3.4.x so there is changes that OSG
master will address this issue.</div>
