gccgo by itself is not really a large C++ program. It's only about
50,000 lines of C++.
Building gcc with --enable-build-with-cxx would get you a large C++
program, but of course i

This is the beta release of binutils 2.21.51.0.2 for Linux, which is
based on binutils 2010 1206 in CVS on sourceware.org plus various
changes. It is purely for Linux.
All relevant patches in patches have been applied to the source tree.
You can take a look at patches/README to see what have been

Ian has stated that he thinks this is a really bad idea. I haven't
approved the patch because I value Ian's opinion, and can see why he
thinks it is the wrong way to go. O

This sounds like
I am writing a plugin that should dump out function declarations and

I'm confused. Why isn't "abort" the function that you want?
After looking on the internet on the term "dumping core" I noticed that
one had to write a piece of code to cause the crash.
I noted that one had to know what to do to cause the crash to get the
dump and gathered that while computer scientists and most engineers know
how to do this, it is not so ob
