G'day Drew,

It's been a few years, but I'm helping clean out Perl 5 bug reports. ;)

Perl 5.8.0 was known to have quite a few issues, and there's a good
chance there's one of them. I'm assuming that Storable is working fine
under 64-bit Solaris now. If it's not, please respond to this ticket
(which will re-open it), and we'll take a look.

Cheerio,

Under 5.10.0, Solaris, with 64 bit integers, ext Storable still fails
badly.
Let me know what other information I can include to help get this
resolved.

Can you send the output of perl -V?
Was it compiled with -Duse64bitall or with -Duse64bitint?

On cpanteters I see the following reports of Solaris for Storable
(from 5.10.0)​:

http​://www.nntp.perl.org/group/perl.cpan.testers/2008/06/msg1668441.html :
use64bitint=undef, use64bitall=undef

http​://www.nntp.perl.org/group/perl.cpan.testers/2008/04/msg1296110.html :
use64bitint=define, use64bitall=undef

http​://www.nntp.perl.org/group/perl.cpan.testers/2007/11/msg811340.html
use64bitint=define, use64bitall=undef

And/or is it possible that you build perl-current (blead) to see if
there is an improvement there? (check perldoc perlhack)

Kind regards,

Bram

fails badly.
Let me know what other information I can include to help get this
resolved.

Can you send the output of perl -V?
Was it compiled with -Duse64bitall or with -Duse64bitint?

On cpanteters I see the following reports of Solaris for Storable
(from 5.10.0)​:

http​://www.nntp.perl.org/group/perl.cpan.testers/2008/06/msg1668441.html
:
use64bitint=undef, use64bitall=undef

http​://www.nntp.perl.org/group/perl.cpan.testers/2008/04/msg1296110.html
:
use64bitint=define, use64bitall=undef

http​://www.nntp.perl.org/group/perl.cpan.testers/2007/11/msg811340.html
use64bitint=define, use64bitall=undef

And/or is it possible that you build perl-current (blead) to see if
there is an improvement there? (check perldoc perlhack)

Kind regards,

Bram

Turns out that under sparc, use64bitint and use64bitall are implicitly
enabled, so that wasn't it.

But in any case, these failures appear to be gone in newer versions of
Perl, so I vote to close this.

Brian has now also built 5.10.0 on his Sparc Solaris machine, 64 bit, and
can't replicate it.

Looking at the original bug report​:

  Received signal #11, SIGSEGV [default]
  siginfo​: SIGSEGV SEGV_MAPERR addr=0x0000000C

and

  :​:stack
  Perl_sv_setiv+4(10023fc60, 0, 10036b3a0, 23fc00, 100000000, 1)
  Storable.so`init_perinterp+0x150(0, 38, 0, 115908, 0, 100270eb0)
  Storable.so`boot_Storable+0x7d4(570, 10023fc60, 10023fc60, ffffffff7d519638, 400, 8)

I think that it's attempting to read the SvFLAGS() on a NULL SV pointer​:

void
Perl_sv_setiv(pTHX_ register SV *sv, IV i)
{
  dVAR;
  SV_CHECK_THINKFIRST_COW_DROP(sv);
  switch (SvTYPE(sv)) {

which will be at offset 0xC on a machine with 64 bit addresses (and a 32 bit
U32 types. ie not-a-Cray)

Which "can't happen", as the calling code should have allocated a new SV
already, and be dereferencing it via SvRV().

Given that the build is optimised​:

  optimize='-O',

it's reminding me of problems we've had with another routine in sv.c which
Sun's (current) compiler doesn't like at -xO3.

So I'm not sure whether it's a subtle bug in the compiler's optimiser, or
a subtle bug in the perl source code. In that, the perl source code is
strictly written in "something not entirely unlike C", given that it
breaches the C standard's requirements on aliasing, accessing the same data
via cast and uncast pointers left right and centre.
(If the source *were* strictly conformant, we'd not be insisting that gcc
compile it with -fno-strict-aliasing)

But I think we have to close the bug as we know that current Sparc compilers
can build the 5.10.0 code 64 bit and pass tests.
