[pcre-dev] coverity report

Hi,

Coverity now also analyses the PCRE code (after a few requests from me ;)
I have access to the data through the PHP project, because we bundle PCRE.
For now only one bug was found, and it seems real. I provide details below.

So, it is time for the current and future maintainers of the PCRE code to
ask for access to the Coverity reports
