I'll not list the rest.

I'll note that https://developer.arm.com/documentation/ihi0055/d/ reports
that va_list is based on:

struct __va_list {
void *__stack;
  void *__gr_top;
  void *__vr_top;
  int   __gr_offs;
  int   __vr_offs;
}

so NULL is not type compatible for aarch64.

My guess is an empty va_list needs to be created and used
instead of NULL, following the normal va_list protocol. This
should avoid presumptions about aspects that the language
standard does not specify.



My armv7 contexts fail similarly.

https://developer.arm.com/documentation/ihi0042/latest

indicates that the va_list typedef is for:

struct __va_list {void *__ap;}

So, again, NULL it not type compatible.


[Bryan has seen a variation of this material via comments
on github.]

poudriere-devel was later updated to avoid the type compatibility.
But the update does not follow the va_list protocol in that it
does initialization of a va_list via ={} to supposedly form an
empty va_list. The ={} is not guaranteed by the language (C99+,
say) to assign the same va_list content as va_start would for an
empty match to a routine's ... in its parameter list.

It looks to be that va_start is the only langauge-definition
supported form of initialization of a va_list (and that va_end
is required to close out such an initialized va_list).

So the likes of:

git: 14e5e1370ddb - main - ports-mgmt/poudriere-devel: Update to 3.3.0-1020-g59a87677c Bryan Drewery
and:
git: 4116dc2f1f63 - main - ports-mgmt/poudriere-devel: Update to 3.3.0-1022-g964cf327f Bryan Drewery

may not prove sufficient in general, although it may well "work"
for amd64 where NULL happened to be compatible with va_list
as far as types go. I do not claim a known operational failure
elsewhere, just going outside what the langauge guarantees for
source code to be guaranteed work for a correct language
implementation.


If it builds I don't think it will matter beyond that. The va_list is only used if the msg param is non-NULL, which it always is in this case.


I mean it is always _NULL_ in this case so not a problem.

See external/sh/error.c verrorwithstatus().
