[Issue 10176] New: new atexit() call to atexit(ldap_exit_tls_destroy) in 2.5.17 crashes AIX application

https://bugs.openldap.org/show_bug.cgi?id=10176 Issue ID: 10176 Summary: new atexit() call to atexit(ldap_exit_tls_destroy) in 2.5.17 crashes AIX application Product: OpenLDAP Version: 2.5.17 Hardware: Other OS: Other Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: philip.miloslavsky(a)gmail.com Target Milestone: --- We have a long standing openldap application that's being ported from 2.4.58 to 2.5.17. On ppc AIX (but not on linux for which we also build), when we exit the main application we get a crash in exit() because it is trying to run the atexit which LDAP regsitered, but ldap has already been unloaded and the unloading caused that atexit function pointer to become zero. So I tracked it to this line of code in ldap 2.5.17 that was not there in 2.4.58 libraries/libldap/tls2.c: atexit( ldap_exit_tls_destroy ); If I remove that line of code, my issue goes away. So, now on to dlcose and atexit. So we have a main kernel (irisdb), a C++ library (ldap.so) that we wrote that calls ldap client libraries, and the 2 actual openldap libraries which ldap.so is linked against. During irisdb exit (the h command) irisdb does call dlclose on ldap.so, which as a side effect results in the unloading of the 2 official openldap libraries, but no one calls unatexit() (on the 0x09001000a04947a8 below). After the 3 libraries are unloaded, the atexit registration is still there but its been replaced with zeroes. At what point in this process should we call unatexit or some LDAP function and why does this sequence of events work right on linux but not AIX?
