If confusion leads to people doubting which one to use and therefore reading
about their deficiencies before they do, it might be a good thing to have IMHO.

Replacing SEALLOC with WXALLOC will fix the crashing when fork() but will
result in a slower/more resource hungry library, and so it might be unwise to
do (and worse if forced into AFAIK).

Either way most users of PCRE are better of fixing their security policies than
using either alternative option, in most cases, and definitely if they care
about performance.
