Public bug reported:
While attempting to debug a simple C++, program, GDB crashes. The
program is below:
$ gdb
GNU gdb (Ubuntu 7.7.1-0ubuntu5~14.04.2) 7.7.1
...
(gdb) file ./cryptopp-test.exe
Reading symbols from ./cryptopp-test.exe...done.
(gdb) r
Starting program: /home/user/cryptopp-test.exe
Traceback (most recent call last):

ImportError: No module named 'libstdcxx'

**********
This appears to be a Debian bug from February, 2013:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=701935.
**********
I'm on Ubuntu 14.04, x86_64 fully patched. I'm using Gnome-Fallback
desktop (it seems many think everything is a tablet now. I'd like to get
a hold of the drugs the folks at Microsoft, Fedora, Ubuntu (etc) are
using for recreational purposes, too).

The program below is going to provide (or not provide) heuristic
evidence of a bias in the Random Number Generator. The crash occurs with
different symbol levels (-g) and optimizations (-O).
