The following short program causes the "compiler proper" part of
G++ 1.32.0 (i.e. the c++ program) to abort.

Commenting out the call to init causes the abort to go away, and
the error messages then produced reveal that this program has
some apparent semantic errors.  The results of compiling this
program are:

   g++ -v -B./ -S x02.cc
   g++ version 1.32.0
    ./cpp -+ -v -undef -D__GNU__ -D__GNUG__ -Dmc68000 -Dsun -Dunix x02.cc /tmp/cca06039.cpp
   GNU CPP version 1.32
    ./c++ /tmp/cca06039.cpp -quiet -dumpbase x02.cc -noreg -version -o x02.s
   GNU C++ version 1.32.0 (68k, MIT syntax) compiled by CC.
   In function void leaf::init (struct handle &):

   Failed assertion at  __LINE__ 992 of `cplus-convert.c'.
