It doesn't even get as far as main(), let alone parsing and using the
$ gdb r.terraflow
Program received signal SIGABRT, Aborted.

The assert is triggering in the constructor for a static variable
within the GEOS library (linked in by GDAL).
static Profiler *internal_profiler = new Profiler();
This gets called before main(), but the customised "operator new()" in
lib/iostream doesn't work until the memory manager has been
initialised, which doesn't occur until G_parser() has been called.
