Description:
------------
OS: SunOS westland-dev 5.10 Generic_118833-36 sun4v sparc SUNW,Sun-Fire-T1000

Extensions Installed:
- apc (not enabled on cli)
-sphinx Revision => $Revision: 1.15 $

Running the code below from the CLI generates a core dump.
Sphinx Extension was built with GCC (gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath)).

Reproduce code:
---------------
<?php

$cl = new SphinxClient();
$cl->SetServer( 'localhost', 3312 );
$cl->SetLimits( 0, 1, 1000 );
$res = $cl->Query( '' );
var_dump( $res );

Actual result:

Please rebuild PHP with --enable-debug (and recompile PECL/sphinx after that if you compiled it as a separate extension).
See also http://bugs.php.net/bugs-generating-backtrace.php

[2008-11-17 09:47 UTC] nobleclem at fatalexception dot us

We performed the rebuilding as requested and here is the new backtrace:

The only thing that has changed this time is our sysadmin upgraded to php 5.2.6 when debug was enabled.

I don't see any differences, the debug symbols are still missing.

[2008-11-17 10:45 UTC] nobleclem at fatalexception dot us

So I noticed APC was tossing an error and thinking that might have cause the debug symbols not showing I had it disabled and reproduced the core dump and backtrace only to get the same thing as in my previous note.

Not sure if this will help but here is how our PHP is currently configured on this system.  Also any suggestions for getting the debug information you are looking for or is using pecl sphinx on solaris a lost cause?

Not good..
Try adding -g3 to CFLAGS when building the extension (or whatever flag enables debug info for the compiler you use).

[2008-11-18 14:15 UTC] nobleclem at fatalexception dot us

Ok we rebuilt PHP and the sphinx extension with the -g3 flag and here is the new backtrace.

I can see that PHP now does have debug symbols, but sphinx.so is still missing them.
Please make sure that the extension itself is built with -g3 flags and doesn't have any other -gN flags defined.

[2008-11-20 14:28 UTC] nobleclem at fatalexception dot us

Sorry about that. I think we have it this time.

I looked at line 235 and I am not sure what the problem might be.

Much better now, thanks. Btw, you can skip these "Reading symbols from .. Loaded symbols ..", they're useless anyway.

Okay, please paste the output you get with these commands in GDB console (type them after the crash):
p mva
p mva[0]
p mva[k]
p k
p i
p *result

Thanks in advance.

Yea I wasn't sure if they would be of use or not.

Also we were digging into some of the libsphinxclient code and found a comment that might be causing some headache.

sphinxclient.c line 1499.

Please check if the following patch fixes it for you:
http://dev.daylessday.org/diff/sphinx_bug15033.diff

[2008-11-21 10:18 UTC] nobleclem at fatalexception dot us

That patch worked perfectly. No more core dumps.

Thank you for your help figuring this out.

[2008-11-21 10:19 UTC] nobleclem at fatalexception dot us

sorry should have set the status to closed.

[2008-11-21 10:21 UTC] tony at daylessday dot org

Ok, thank you for your patience.
