The problem arises if your C++ program uses static constructors and/or
destructors. A big problem with such programs is that the compiler
has to insert a call to a special routine which calls all of the constructors
*before* the program starts executing for proper. This cannot be done
during the initial compiling stage as the compiler cannot know what
constructors will be called from other modules, e.g. the constructors
for the standard streams (cout, cin, cerr) in libC.a. The solution used
depends on whether you are working on a system with libld.a. If you are,
a program called patch is used to build a list of pointers to static
constructors and patch it into the executable, On other systems nm(1)
is run on the executable and the output piped into a special program
called munch. This spots symbols which are static constructors and generates
a C file which is then compiled and the whole executable is relinked (now
you see why compiling/linking can take an age!)

The reason your program bus errored is that the stream package is not
being initialised.
