This is a bug report for perl from abigail@abigail.be,
generated with the help of perlbug 1.41 running under perl 5.28.0.


-----------------------------------------------------------------
[Please describe your issue here]

When composing my previous bugreport with perlbug, when trying
to save the report to a file (using the 'f' option), perlbug
died with the message:

    This shouldn't happen

generated in lib/Text/Wrap.pm, leaving just an empty 'perlbug.rep' file.

This may be triggered by the included output from one of the tests:
in included huge lines, with lots of NUL characters.


[Please do not change anything below this line]
