Please give your configuration, because this does not segfault for me:

PCRE2 version 10.20 2015-06-30
re> /(((?3)))((?1))/
data> abcd

Failed: error -52: nested recursion at the same subject position

That was with pcre2test. Using pcre2grep does not crash either. It may be that
your PCRE2 configuration is different. What is the output from "pcre2test -C"?
