Re: Any news on CPAN bug 32309 in DBI - faulty definition of DBIS for big-endian 64-bit machines with MULTIPLICITY

I've been too busy recently for various reasons to give it much time.
The macro is complex because (as I recall) it was setup to be an lvalue.
ActiveState supplied the patch many years ago when they added PERL_OBJECT.
The tricky question is: do some drivers still need it to be an lvalue?
I think the answer is no.
I suggest someone test and post a patch here that others can try out
on a variety of drivers.
Tim.

CPAN Bug 32309 was created recently, but I'm told that the underlying.
problems was first reported in 2003 (though I only see DBI bugs dating back
4 years or so, so I can believe that the original bug report has now been
lost). The new bug entry includes a plausible solution (albeit not as a
patch file, but it is a one-line change).

It does not appear to have been fixed in DBI 1.601. The problem appears not
to affect most people - it requires a big-endian machine (such as IBM
PowerPC) running in 64-bit mode[*] where 'sizeof(int) != sizeof(void *)'
with MULTIPLICITY (or PERL_OBJECT or PERL_CAPI if I'm reading
DBIXS.hcorrectly) set.
Is there a reason why this cannot be fixed - or should not be fixed?
Colleagues of mine in India have asked about this. Is there a timeline I
can offer them for when this might be fixed in a general release of DBI?

[*] 64-bit mode: or it might be on a 32-bit machine with 16-bit ints, I
suppose, but that's not a plausible choice these days.
