Bug Type: LDAP related
Operating System: Red Hat Enterprise Linux AS rele
PHP Version: 4.4.5
New Comment:
Here is the information I got from Oracle on this. It looks like an
issue in the LDAP API implementation:
Bug 4944940
Problem statement:
INCORRECT USE OF NZ API, NZDSI_INITIALIZE, CAUSES CRASH
The nz API nzdsi_initialize is thread-unsafe and should be used only
during startup/initialization. In the OCI stack the ldap API calls this
API for each thread which causes the app to crash. As a temporary fix we
have made some changes in nz to resolve that issue (see bug 4405452).
But this needs to be fixed in ldap API implementation. The nzctx
context should be created just once.
The stack when nzdsi_initialize is invoked -
@ start_thread
@ thread_main
@ oci_connect
@ OCIServerAttach
@ kpuatch
@ kwfcinit
@ kwfnran
@ niqname
@ nnfsn2a
@ nnfun2a
@ nlolgobj
@ nnfgrne
@ nnflboot
@ nnflcgc
@ nnflobc
@ nnflgcp
@ nnfloiddisco
@ ora_create_discov_hdl
@ gslccx_Getgsluctx
@ gsluizgcGetContext
@ gsluinit
@ nzdsi_initialize # initializes nz context

Sure. Just look at your backtrace, everything there points to the
Oracle Instant Client.

Can you explain what exactly indicates to you that the Oracle instant
client is the problem?

Ok, feel free to reopen the report when/if you have any additional
information.

I've rebuilt php without the Oracle component and the problem indeed
has gone away. I will follow up with Oracle. Thanks for the help.

A segfault somewhere deep inside the Oracle Instant Client doesn't seem
PHP related to me.
Did you try reporting this to Oracle developers?
