I can't reproduce your results on Linux.  I suspect there's eomething
wrong with your build of bash, or possibly with your system's regex
functions (in libc).

Even on HP-UX, I still can't reproduce it.  Granted, my HP-UX systems are
PA-RISC, running older versions of HP-UX, and running bash 4.3, but still.

You also appear to be using bash's builtin malloc, rather than the
system's malloc from libc.  I'm not sure whether that's relevant here,
but it's noteworthy.
