Strange.  Which binutils do you use?  I have 2.12.90.0.15 here.

It is a call to std::terminate() which leads to an abort then.  On gcc
HEAD revision, a "terminate called after throwing an instance of
'int'" is printed before aborting.

The stack traces are:

Well, this is perfectly clear to me, but it anyway makes a difference.
