This turned out somewhat nasty.

The segfault was only happening in the libFLAC++ code and only when
compiled with -DDEBUG. Debugging with GDB and Valgrind only managed
to track the problem down to code where constructors or destructors
would be.

I then added -Weffc++ to CXXFLAGS and found a number of classes which
contained pointer data members but which had no copy constructors or
assignment operator methods. The other problem we related in missing
data member initializers.

Fixing all these issues made the segfault disappear.
