Not that deep actually.  sre.py line 168 is this:

    if sys.hexversion >= 0x02020000:

You're using restricted mode (the rexec module) and this apparently
doesn't provide sys.hexversion.  This is a shallow bug; it's already
fixed in Python 2.3 (CVS).

Probably those versions of Python didn't have the test for
sys.hexversion; it's testing whether this is Python 2.2 or higher.

A workaround would be to set sys.hexversion to 0x02020000 (or to 0 if
you're not sure which Python version you're using) before importing
sre for the first time.
