D program which fails

Running the attached program with the attached file (using the latest dmd,
druntime, and Phobos), results in this Assertion failure:

It happens on both 32-bit and 64-bit Linux. I don't know if it happens on other
OSes (though I assume that it does). I was trying to run an example from the
newsgroup to benchmark the old std.regex vs the new one, and while the old one
worked, the new one failed with the AssertError.
