[gentoo-bsd] segfaults in programs compiled with g++

[Mehul Ved]

In my earlier mail, I had mysqld segfaulting. On looking further I see
many other programs like nmap, webmin are giving errors. While
rebuilding the system with
emerge -e system
I got an error message from groff complaining of non-working C++
compiler.
Thus, I tried compiling a simple C++ program from a friend, it compiles
fine but I get segfault on it, too, while running.
I am attaching groff error and g++ -v
