build perl module Proc::ProcessTable with perl of 5.16.1 and faild in the phase of "make test"

Question

I am building the Proc::ProcessTable with perl of 5.16.1

make's output:

Skip blib/lib/Proc/ProcessTable.pm (unchanged)

It seems ok.

make test's output:

Thank you !

This is not a full answer.

The error is "Not a CODE reference" reported at DynaLoader.pm line 213:

  boot:
    my $xs = dl_install_xsub("${module}::bootstrap", $boot_symbol_ref, $file);

    # See comment block above

    push(@dl_shared_objects, $file); # record files loaded

    &$xs(@args);   # <- line 213

This means whatever was returned by dl_install_xsub is not a coderef. More specifically, it can't be undef, a number, or a string because those would result in different error messages. Therefore $xs contains some other type of reference at that point.

dl_install_xsub (part of DynaLoader) is a thin wrapper around newXS_flags (part of perl). newXS_flags returns a CV * (perl type: pointer to "code value"). And at this point I'm stumped because I have no idea how this could possibly result in a non-coderef.

Possible avenues for further investigation: Use the perl debugger to put a breakpoint in DynaLoader.pm line 213 and check what's actually in $xs, then work backwards.
