This is a bug report for perl from l.mai@web.de,
generated with the help of perlbug 1.40 running under perl 5.25.6.

[Please describe your issue here]

op/utf8decode.t .. 1/? # Failed test 224 - Only expected warning for 3.5.2 at op/utf8decode.t line 50

op/utf8decode.t .. Failed 4/710 subtests


This test has been failing for me since commit
2b5e7bc2e60b4 ("utf8n_to_uvchr(): Note multiple malformations").

Does anyone know what's up with that?

Possibly related to building on a 32-bit platform?
