in thread Unit test of script fails unless Test::Warnings is used?!

Because Test::Warnings runs a test of its own, so the harness is satisfied. Output of your test script using Test::Warnings under --verbose: 

$ prove -lrv 11107390.t
11107390.t .. 
ok 1 - no (unexpected) warnings (via done_testing)
1..1
ok
All tests successful.

Hope this helps!


The way forward always starts with a minimal test.
