           Summary: [trans-mem] call to an undefined clone
           Product: gcc
           Version: trans-mem
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org

Created attachment 23569
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23569
testcase showing that.

In this testcase, the std namespace is not transactionalized and a class, Unit
is using implicit destructor std::string for its member.
In this class Unit, the destructor is cloned but the implicit destructor for
std::string is transformed to a transactional one _ZGTtNSsD2Ev. Unfortunately,
_ZGTtNSsD2Ev is not defined and I think the correct behaviour should be
switching to irrevocable mode and then call the unsafe _ZNSsD2Ev.

Aldy: this happens in the Glob2, one undefined reference that we got.
