TagLib 1.9.1 crash using C++11

Hi,

The following particulate from your stack trace shows that the second argument to insert() is a TagLib::MP4::Item not a TagLib::StringList ...
> insert(TagLib::String const&, TagLib::MP4::Item const&)

However, I did wrap your sample code with the rest of the necessities and it tests fine using GCC c++11 on Windows, FreeBSD and OS X.

I shall try CLang when it's done building ...

Might I suggest a slight code change: mp4File->tag()->itemListMap().insert("\251grp", TagLib::MP4::Item(sl));

TagLib master has new accessors MP4::Tag::item(const String &key) and MP4::Tag::setItem(const String &key, const Item &value) for this in the next release.

-Enjoy
: )_~

Hmmm. taglib2 didn't work either. A simpler stack trace, but looks like the same crash essentially:

0 ... 0x0000000108214283 std::__1::map<TagLib::String, TagLib::MP4::Item, std::__1::less<TagLib::String>, std::__1::allocator<std::__1::pair<TagLib::String const, TagLib::MP4::Item> > >::operator[](TagLib::String const&) + 211
1 ... 0x00000001082132f1 TagLib::Map<TagLib::String, TagLib::MP4::Item>::insert(TagLib::String const&, TagLib::MP4::Item const&) + 97

Is anyone successfully using the itemListMap with C++11? I can't read from it either, though that doesn't crash.

Sadly, current master didn't improve matters, so I imagine neither will that specific tag.
