            Bug ID: 227104
           Summary: sysutils/p5-BSD-Process list method causes
                    segmentation fault
           Product: Ports & Packages
           Version: Latest
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: Individual Port(s)

The list method of BMD::Process causes a segmentation fault.

$ perl -MBSD::Process -e 'print $BSD::Process::VERSION';
0.07
$ freebsd-version
11.1-RELEASE-p8
$ perl -e 'use BSD::Process; my @pid = BSD::Process::list;'
Segmentation fault (core dumped)

The perl version is v5.24.3

This also happens if you use the following command which is taken from the CPAN
page (http://search.cpan.org/~dland/BSD-Process-0.07/Process.pm)

$ perl -e 'use BSD::Process; my @pid = BSD::Process::list; for my $p (@pid) {my
$proc =  BSD::Process::info($p); print "$p $proc->{ppid}\n"; }'
Segmentation fault (core dumped)

Extra information:
This error appears to occur because the XS code does not handle multiple
returned values properly and corrupts the stack, specifically the mPUSHi macro
at line 504 of Process.xs does not appear to extend the stack. If the loop
there is preceded by an EXTEND(SP,nr) the test works. (Diagnosis by others)
