I presume that the actual regex that you want to pass to PCRE is

\A[ \n\r\t]*<!\[CDATA\[([^\]]+)\]\]>

Well, yes, it will. After [CDATA[ your pattern expects a sequence of
not-] followed by ]] and your test string doesn't have that. After a
sequence of not-] your test string has ]:0]]

It doesn't match for me when I test with pcretest.

> <![CDATA[test 0 test1 \ntest2 runPackage:0]]></log>\n</xmlreport> ###(no square brackets inside CDATA)


That one does match for me.
