On a 4.3BSD Vax 8650, I have g++ 1.31 compiled with gcc 1.31, with
fixes by Michael Tiemann to g++/cplus-init.c, g++/expr.c, g++/stmt.c,
and reverse_condition made extern in gcc/jump.c.  I get a segmentation
violation when compiling test4.cc, as included in libg++ 1.25.
gcc-c++ wasn't producing any core file, although it did produce the
``Segmentation violation'' message, and g++ was reporting that gcc-c++
was killed with a fatal signal.  The following change to the g++ code
produced a core file for me:

  }

Then I could produce the following:

Background: (repeated from my last posting - new stuff after diff)

On a 4.3BSD Vax 8650, I have g++ 1.31 compiled with gcc 1.31, with
fixes by Michael Tiemann to g++/cplus-init.c, g++/expr.c, g++/stmt.c,
and reverse_condition made extern in gcc/jump.c.  I get a segmentation
violation when compiling test5[ab].cc, as included in libg++ 1.25.
gcc-c++ wasn't producing any core file, although it did produce the
``Segmentation violation'' message, and g++ was reporting that gcc-c++
was killed with a fatal signal.  The following change to the g++ code
produced a core file for me:
