Describe the bug

I'm using jesse to validate a JSON document with a fairly large schema (https://github.com/jdegre/5GC_APIs/blob/Rel-18/TS29510_Nnrf_NFManagement.yaml).

As part of that validation the IPv6 address ::1 is checked against the regex ^((:|(0?|([1-9a-f][0-9a-f]{0,3}))):)((0?|([1-9a-f][0-9a-f]{0,3})):){0,6}(:|(0?|([1-9a-f][0-9a-f]{0,3})))$.

This used to work fine, but suddenly fails when switching to 28.0-rc1.

The code that does the validation is in https://github.com/for-GET/jesse/blob/master/src/jesse_lib.erl#L127-L128.

What it does is essentially:

Subject = <<"::1">>,
RE = <<"^((:|(0?|([1-9a-f][0-9a-f]{0,3}))):)((0?|([1-9a-f][0-9a-f]{0,3})):){0,6}(:|(0?|([1-9a-f][0-9a-f]{0,3})))$">>,
Opts = [{capture,none},unicode,ucp],
re:run(Subject, RE, Opts).

When I run that snippet from a small test module or from the CLI, then it works. However, running the exact same Subject and RE as part of large project results in a nomatch. Compiling the regex first does not change the result.

However, when I replace the re:run expression with: re:run(Subject, binary:copy(RE), Opts) then it also works within the large project.

So far trying to inspet RE with io:format and erlang:display has yield nothing. Is there anything I can do to provide more information?
