Log of compilation

In a simple class (LocalGeometryLock) designed to provide a lock the destructor
appears to be removed by optimization. This can be prevented by either adding a
cout to the destructor or adding __attribute__((optimize("-O0"))) after the
destructor definition. This occurs in the code for a large project which it is
not practical to send. Unfortunately it has not proved possible to reproduce
the issue with a simple test program.
