Bug #50964 for Term-ReadLine-Perl: spurious diagnostic messages in test on Solaris

With perl-5.8.8 on Solaris (8/Sparc, 10/x86) I am getting a lot of spurious output from the test script, when I press the [Backspace] key after the prompt: Enter arithmetic or Perl expression: exit appears. See the attached log for all details. The messages seem all the same: Redefining sub readline::F_BackwardChar at blib/lib/Term/ReadLine/readline.pm line 1669 at /opt/perl_5.8.8/lib/SelfLoader.pm line 164 SelfLoader::_add_to_cache('SelfLoader', 'readline::F_BackwardChar', 'readline', 'ARRAY(0x813febc)', '') called at /opt/perl_5.8.8/lib/SelfLoader.pm line 111 SelfLoader::_load_stubs('SelfLoader', 'F_BeginningOfLine') called at /opt/perl_5.8.8/lib/SelfLoader.pm line 63 SelfLoader::AUTOLOAD(1, 8) called at blib/lib/Term/ReadLine/readline.pm line 1669 readline::readline('Enter arithmetic or Perl expression: ', 'exit') called at blib/lib/Term/ReadLine/Perl.pm line 11 Term::ReadLine::Perl::readline('Term::ReadLine::Perl=ARRAY(0x8091c84)', 'Enter arithmetic or Perl expression: ', 'exit') called at test.pl line 54 Interestingly, this does not show up on Linux (although there is also the uninit value warning): $ perl -Mblib test.pl Use of uninitialized value in bitwise or (|) at test.pl line 33. at test.pl line 33 Features present: preput 1 getHistory 1 addHistory 1 attribs 1 ornaments 1 appname 1 minline 1 autohistory 1 newTTY 1 tkRunning 1 setHistory 1 Flipping rl_default_selected each line. Hint: Entering the word exit would exit the test. ;-) (If feature 'preput' is present, this word should be already entered.) Enter arithmetic or Perl expression: Do you have an idea what could be wrong? Is there anything else which I could contribute to find the root cause? Cheers, Marek
