Well, this is not a result of a bleeding edge compiler. This occurs on
my (now ancient) compiler too. I got to the same result. Martin and me
were trying to get a sensible backtraces instead of the following ones:

Condvar #0 (0x0x7f97580010c8) first referenced by:

(notice those anonymous static functions which makes this output unreadable)

This is an output from a tool that analyses mutex/condvar congestions:
