I don't understand. What program are you using? What is ENTITY? What is
"ADV/ADV"? I am guessing you are using some program that calls PCRE.
Your pattern (test(?C1)) will match the string "test", and then do the
callout. Othewise it will not call out.

Again, I do not understand. What is "dnt_entity_callout"? It is not part
of PCRE.

Who is re-writing? PCRE has no facilities for re-writing. It must be the
application that you are using.
I tried your pattern with pcretest, and it gives the right answer:
PCRE version 7.8 2008-09-05
/(test(?C1))/g
testcallout and testCALLOUT and friday
--->testcallout and testCALLOUT and friday
1 ^ ^ )
0: test
1: test
1 ^ ^ )
0: test
1: test
The lines with ^ are where the callouts happened; they show that PCRE
has matched the string "test", as expected, when the callout is obeyed.
(The ")" at the end is the remainder of the pattern that has still to be
obeyed.)
