Checking the kind of infinities and nans you have...
(The following tests may crash. That's okay.)
Checking how many mantissa bits your doubles have...
Checking how many mantissa bits your long doubles have...
Checking how many mantissa bits your NVs have...
Using our internal random number implementation...
Determining whether or not we are on an EBCDIC system...
Nope, no EBCDIC, probably ASCII or some ISO Latin. Or UTF-8.
Checking how to flush all pending stdio output...
Checking the size of gid_t...
Checking the sign of gid_t...
Checking how to print 64-bit integers...
Checking the format strings to be used for Perl's internal types...
Checking the format string to be used for gids...
getgroups() found.
setgroups() found.
What type pointer is the second argument to getgroups() and setgroups()?
[gid_t]
Checking if your /usr/bin/make program sets $(MAKE)...
It seems that va_copy() or similar will be needed.
What pager is used on your system? [/usr/bin/less -R]
Checking how to generate random libraries on your machine...
Checking the size of size_t...
Checking to see if you have socklen_t...
<socks.h> NOT found.
I'll be using ssize_t for functions returning a byte count.
Checking the size of st_ino...
Checking the sign of st_ino...
Your stdio uses signed chars.
Checking the size of uid_t...
Checking the sign of uid_t...
Checking the format string to be used for uids...
Determining whether we can use sysctl with KERN_PROC_PATHNAME to find
executing program...
I'm unable to compile the test program.
I'll assume no sysctl with KERN_PROC_PATHNAME here.
Determining whether we can use _NSGetExecutablePath to find executing
program...
I'm unable to compile the test program.
I'll assume no _NSGetExecutablePath here.

Updating makefile...
Now you must run 'make'.

If you compile perl5 on a different machine or from a different object
directory, copy the Policy.sh file from this object directory to the
new one before you run Configure -- this will help you with most of
the policy defaults.

Please attach the output of 'perl -V' for the perl you use everyday on the machine on which you were attempting to build these versions of perl.

Also, please post the full arguments you provided to './Configure'.

Thank you very much.

Attempt to build 5.28 (and 5.29) fails with​:

./miniperl -Ilib autodoc.pl
corrupted size vs. prev_size
make​: *** [makefile​:410​: pod/perlintern.pod] Aborted (core dumped)

Full build log attached (sorry, no way to run perlbug)

I tried with perl 5.12.3 (on a ubuntu xenial-like system, patchperl ran here) and this also failed​:

./miniperl -Ilib autodoc.pl
*** Error in `./miniperl'​: munmap_chunk()​: invalid pointer​: 0x000000000185ba40 ***

Probably it would be interesting until which point in perl history this worked...

Per https://rt.perl.org/Public/Bug/Display.html?id=133384 this "option is undocumented, untested, and has probably suffered much bitrot over the years."
