I see 3 different perls in your path. An IBM Perl, An ActivePerl 64b with GCC installed via ppm, and a 32 bit ActivePerl.

ld='C:\Perl64\site\bin\g++.exe', ldflags ='-L"C:\Program Files (x86)\IBM\RationalSDLC\common\lib\perl5\site_perl\5.16.1\MSWin32-x86-thread-multi\lib\CORE"'

My @INC knowledge is poor, but my guess isperlbug ran with ActivePerl 64, which used IBM Perl's Config.pm.

What is the -V of cqperl.exe, not perl.exe?

That messages comes from an incomplete installation of Scalar::Util.
Specifically, when the XS component missing. Reinstalling it will fix the
issue.

'perlbug' and rt.perl.org are for the purpose of reporting bugs in Perl 5 or the Perl 5 core distributions.

Spreadsheet::ParseExcel is not part of the Perl 5 core distribution. This problem should have been reported at:
https://rt.cpan.org/Ticket/Create.html?Queue=Spreadsheet-ParseExcel

Closing this ticket. Should you need further assistance, please note the instructions for bug reporting which the maintainers of Spreadsheet::ParseExcel have posted at that rt.cpan.org page.

Thank you very much.

The problem simplifies to

perl -MScalar::Util=weaken -e1

Scalar::Util is a core module, but it has upstream of cpan. You would be
redirected to report that problem at
https://rt.cpan.org/Ticket/Create.html?Queue=Scalar-List-Utils

That said, you would be told it's a problem with your installation and to
reinstall Scalar::Util. Should you need assistance with that, I recommend
posting on PerlMonks or StackOverflow.

RT Perl#13427 TRIE_STORE_REVCHAR() was creating SvPV()s with no trailing '\0'. This doesn't really matter given the specialised use these are put to, but it upset valgrind et al when perl was run with -Drv which printf("%s")'s the contents of the string.
