I successfully built and tested Perl 5.20.0 on Darwin/PPC when it was released two months ago. I built and tested blead today for the first time since then. I was surprised to get a test failure in t/porting/libperl.c.

When I re-directed the test's STDOUT and STDERR to a file, I got a tremendous amount of "# Unexpected nm output" lines. For the full output, see the tarball attached.

Here is the short version of the output.

I am not getting this failure on Linux x86_64. I have not yet tried this on Darwin x86_64.

Has anything happened lately that would have an impact on this?

Thank you very much.

P.S.​: See attachment for 'perl -V' for the machine that had the failure.

  Add t/porting/libperl.t
 
  For sanity checking libperl.a on those platforms that have one,
  and extra checking for the rare configurations of -DPERL_GLOBAL_STRUCT
  and -DPERL_GLOBAL_STRUCT_PRIVATE which restructure the symbol exports.

#####

So this is not only a new failure in t/porting/libperl.t; it is also the very *first* failure reported in this file, as it was only added by Jarkko on June 25.

Jarkko has communicated to me that this is probably something trivial in the 'nm' output on PPC. He is travelling for a couple of weeks and will look at this upon his return.

Not that that should prevent anyone else from looking at this problem!

Thank you very much.

This failure probably has an OS aspect and a platform aspect. Attached please find two files with the output of t/porting/libperl.t on Darwin x86_64. The file has failures on x86_64, albeit fewer than on the older PPC.

Thank you very much.

Jim asked about marking this skipped on this platform until a fix is in. I think that's fine.

On most platforms, that would show up as "unexpected TODO pass," which is the
wrong kind of visibility. If the TODO is platform-specific, I'm not sure this
is really going to add any kind of visibility, is it?

Curiously it doesn't fail for me on Mavericks with Intel​:

Looks like your PPC is 10.4 Tiger and your x86_64 is 10.7 Lion?

What's your "/usr/bin/nm -m ../libperl.a" output? Mine (that passes
tests) is attached.
