Sigh. Those are always the hardest bugs to find.

Include the escape sequence \>dd (for example, \>10) in the subject
text. See the pcretest.1 man page for a full list of all the possible
escapes. However, see below...

It doesn't sound as though pcretest will help you. I'm afraid I am not a
C++ person, so I'm not really familiar with the pcrecpp stuff; I work
down at the C level. Needless to say, a trivial test of your regex with
pcretest on Linux does not show any problem. (I cannot test on Windows.)
