1868    This error is returned when \fBpcre_exec()\fP detects a recursion loop within
1869    the pattern. Specifically, it means that either the whole pattern or a
1870    subpattern has been called recursively for the second time at the same position
1871    in the subject string. Some simple patterns that might do this are detected and
1872    faulted at compile time, but more complicated cases, in particular mutual
1873    recursions between two different subpatterns, cannot be detected until run
1874    time.
