PHP :: Bug #20021 :: core when execute phpinfo()

[2002-10-22 03:39 UTC] sniper@php.net

Please try using this CVS snapshot:

  http://snaps.php.net/php4-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-latest.zip

[2002-10-22 04:48 UTC] scalero at datadec dot es

At startup:


# /usr/internet/httpd2/bin/apachectl start                                
Unaligned access pid=127407 <httpd> va=0x3fffffec0ac pc=0x3ffbff773f0 ra=0x3ffbff773e4 inst=0xb4010000
Unaligned access pid=127407 <httpd> va=0x3fffffed8dc pc=0x3ffbff773f0 ra=0x3ffbff773e4 inst=0xb4010000
/usr/internet/httpd2/bin/apachectl start: httpd started

And continues with the problem, this is de gdb out:

Loaded symbols for /usr/shlib/libclu.so
#0  0x3ff800e1f28 in kill () from /usr/shlib/libc.so

warning: Hit heuristic-fence-post without finding
warning: enclosing function for address 0x14068bf18
This warning occurs if you are debugging a function without any symbols
(for example, in a stripped executable).  In that case, you may wish to
increase the size of the search with the `set heuristic-fence-post' command.


With the snapshot another scripts make cores.

Many thanks.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

If this is insufficient, I can attach the core to a mail for "sniper@php.net".

[2002-10-22 11:58 UTC] iliaa@php.net

Do you have any CFLAGS exported that could cause the debugging symbols to be lost?

[2002-10-22 12:04 UTC] scalero at datadec dot es

How can I see the 'CFLAGS'?

The library '/u01/app/oracle/product/8.1.7/lib/libwtc8.so' is created when Oracle is installed in the system.

[2002-10-22 12:29 UTC] sniper@php.net

What is the 'ldap_sdk' here? Try compile php without --with-ldap

[2002-10-22 12:30 UTC] sniper@php.net

Forgot to mention this: On some systems you need to have apache httpd also linked with libpthread.so when PHP is linked with oci8..

[2002-10-23 01:52 UTC] scalero at datadec dot es

I rebuild Apache with: 'LDFLAGS=-lpthread', when I execute ldd httpd:


        Main  =>   httpd
        libpthread.so  =>   /usr/shlib/libpthread.so
        libm.so  =>   /usr/shlib/libm.so
        libc.so  =>   /usr/shlib/libc.so
        libexc.so  =>   /usr/shlib/libexc.so

And the 'ldap_sdk' are the LDAP libraries of Netscape, I use PHP for access a LDAP directory.

---

Please read these instructions again and try the 
method of running httpd under gdb.

Also, try compiling PHP without --with-oci8.
If no crash happens, then make --with-ldap to use 
the oracle provided ldap by passing it the same path as for oci8.

From the howto for generating backtraces:

"Run httpd -X under gdb with something like: 
 # gdb /usr/local/apache/sbin/httpd 
 (gdb) run -X 

 Then use your web browser and access your server to force   
 the crash. You should see a gdb prompt appear and some 
 message indicating that there was a crash. At this gdb
 prompt, type:             

 (gdb) bt 
"

Can you try this? Also, try compiling PHP without --with-oci8. If no crash happens, then make --with-ldap to use the oracle provided ldap by passing it the same path as for oci8. And use the latest snapshot for these tests!

[2002-11-04 11:19 UTC] scalero at datadec dot es

Definitively gdb not run correctly under tru64 v5.1. 

In any case, I try compile php with other options:
- Without "oci8" --> I obtain the core
- Without "ldap" --> OK!!!
- With oracle provided ldap --> Not compile

The problem is the ldap library "ldap_sdk" provided by Netscape, but I use Netscape directory server. The ldap funtions that I use in my scripts works OK and only phpinfo() crashes. 

I don?t understand it...

[2002-12-01 16:45 UTC] sterling@php.net

Try enabling thread safety support in php, and reopen a new bug if you still have this problem.
