Hi,

I've compiled my own Perl 5.18.1 on AIX 7.1 TL2 SP3 with IBM XL C/C++ v12.1.0.5
I've installed a few additional modules and one of them failed a test.
I've reported the error encountered​: https://groups.google.com/forum/#!topic/mojolicious/T34XZX72LaA
After a few tests, we've been able to target the issue in the getsockopt() subroutine of IO​::Socket. It seems that this subroutine does not meet the condition to unpack on AIX while it should do it.
I've opened a ticket against IO​::Socket​: https://rt.cpan.org/Public/Bug/Display.html?id=91183
However, it seems that IO​::Socket is now considered as part of Perl5 core and therefore this is why I'm opening this ticket today.

Best regards,

John K. patch looks good but can you test it?

Hi,

I've tested it and it works.
Is it too late to get this in 5.18.2?
If so, could this be added for 5.18.3 and 5.19/5.20?

Hi,

Is it possible to get the attention of a Perl porter who could commit this
change so it could be part of the next Perl releases ? (5.18.3, 5.19.x,
5.20.x)

I've added it to the 5.18.3 blockers to be reviewed.

Meanwhile, this needs review for 5.20.0 as well, and I'll flag it for that too in a moment.

Essentially this change was applied as ee2276e by jhi.

I vote to backport to 5.20, any others?

Makes sense to me. (I actually understand it, believe it or not.) +1.

+1 - though that's from someone with no experience with AIX
