Hi to all.<br>
<br>
It appeals that TagLib::ASF::Tag::addAttribute has a memory leakage bug,<br>
<br>
ASF::File f( filename, false );<br>
<br>
ASF::Tag *asfTag = f.tag();<br>
<br>
<br>
> ASF::Attribute atb( ByteVector( 10000000, 0 ) );<br>
<br>
asfTag->addAttribute( "Test", atb );<br>
<br>
f.save();<br>
<br>
<br>
<br>
The above code will cause memory leakage, if you increase the size of the<br>
asf attribute, things get even worst.<br>
<br>

Best Regards<br>

<br>
Can you please be more specific? Valgrind on examples/tagreader<br>
reports no real memory leaks when running on a WMA file. Everything in<br>
ASF::Attribute is reference-counted, it will get deleted when the last<br>
instance runs out of context.<br>
