Intrusive multiset: insert doesn't preserve size counter when comparator throws

[michal.pecio@…]

multiset::insert() doesn't seem to preserve the "constant time size" counter when comparator throws despite supposedly providing strong guarantee.

Other containers and methods might also be affected, I haven't tested them.

The problem definitely exists in 1.44 and, if I've configured my compiler properly, in svn.

I'm going to attach a code sample which triggers the bug.

Updated SVN code, code sample works correctly. Thanks for the report.
