/*
I get:

c(0) this=0x7fff13f56120
c(0).f() this=0x7fff13f56120
nop()
~c(0) this=0x7fff13f56120

I'm expecting (where .... are non-zero values):

c(0) this=...
c(...) this=...
c(...).f() this=...
nop()
~c(...) this=...
~c(0) this=...

Some people have suggested that RVO is happening.  However:

- would RVO take precedence over program semantics?
- I didn't use optimization flags (default is -O0)
