Source: libtest-differences-perl
Version: 0.64-1
Severity: important
User: debian-perl at lists.debian.org
Usertags: perl-5.28-transition

This package fails to build with perl 5.28.0-RC1 (currently in
experimental).

This seems to be related to verbose test output. 

$ prove -b t/column-headers.t 
t/column-headers.t .. ok   
All tests successful.
Files=1, Tests=2,  0 wallclock secs ( 0.02 usr  0.00 sys +  0.13 cusr  0.02 csys =  0.17 CPU)
Result: PASS

$ prove -v -b t/column-headers.t 
t/column-headers.t ..
