The patch

The problem is a bug in our port of PCRE - that a read may take place from the
first character in an empty string.  For the time being, revert to using a
valid pointer in the data segment rather than an invalid non-null pointer into
the zero-page for the empty string's data pointer.  A better fix for this will
be to remove PCRE.
