Public bug reported:
* Description: Ubuntu 14.10
Release: 14.10
* 0.5.7-3ubuntu1
* I expected that application linked with msgpack3 passed all valgrind memory
checks
* undefined behaviour in msgpack::unpacker::next - malloc/delete
===================================
In 0.5.7 version msgpack::unpacker holds zone in std::aut_ptr.
In msgpack::unpacker::next on line 234 we can see this code:
result->zone().reset( release_zone() );
Look here:
https://github.com/msgpack/msgpack-c/blob/cpp-0.5/src/msgpack/unpack.hpp#L234
release_zone() implemented in C-style with malloc(). Line 234 causes an
undefined behaviour: malloc/delete.
This bug and many others fixed in 0.5.9.
0.5.9 and 0.5.7 have the same API, so there is no reason to have old version of
msgpack in Ubuntu repo.
