Well the backtrace is quite simple:
GNU gdb 6.2.1
This GDB was configured as "sparc-sun-solaris2.9"...
Core was generated by `./php ./x.php'.
Program terminated with signal 11, Segmentation fault.
[SKIPPED READING SYMBOLS]
(gdb) bt
#0 0x002c4b74 in shutdown_memory_manager ()
#1 0x0027d3d0 in php_module_shutdown ()
#2 0x0033525c in main ()

Please, generate a gdb backtrace, it works fine for me.

Yes it works perfectly for FDs but introduces segfault at php shutdown,
when I use the code:
for ($i=0; $i < 200; $i++)
{
$c1 = @ociplogon($valid_user, $valid_password, $db);
}
Note that the credentials are valid here.
It seems that the ENV handle is freed more than once somewhere :-)

Well, yes, of course Solaris & Linux clients are different, but initial
report states that this issue was reproduced under Linux.
I updated the patch (revers the old one before applying this), you can
get at the same URL.
Btw, this version of the patch should fix another issue: it reports
memleaks for me with ocilogon() and invalid password/login.
Try it out and tell me if it works under Solaris.

P.S. I think you can't reproduce this under Linux because of the Oracle
Client software design for Linux may be quite different from Solaris'
one.

Tried your patch, it resolves the problem partially.
In fact, only one bad case remains:
C'. using ocilogon()/ociplogon() with invalid credentials.
I mean if you use ocinlogon() with invalid credentials, all works
because the ENV handle is freed for exclusive session explictly by your
patch. So I suppose you should free ENV handle explicitly in the case of
a failed connection/invalid logon also.
Then all will work fine, hope :-)
How about these patches for 4.3.x?
