Well, the issue with these kind of testcases / bugs is that we cannot
easily mark them as dups of each other because nobody separates the
issues the testcases show into separate bugreports (which could be
individually marked as regression).  So the bugs tend to stay open
forever, with much confusion as to what issue (still) exists or has
popped up again or new.

Tracking the testcases so we see when they regress again is important
(and gcc.opensuse.org/c++bench/random is just a lame attempt, because
C++ issues keep breaking testcases and because the machine has not
enough memory to keep up with the task - and the scripting is lame, too ;))

I realize this meta-bug is a bad attempt at making the important regression
numbers look better ;)
