Greetings, We noticed the following in the error log on one of our Apache 2.2.11 instances: sasl.c:74: failed assertion `ld != NULL' [Mon Mar 02 09:25:17 2009] [notice] child pid 25633 exit signal Abort (6) After exhaustive research that included running Apache inside gdb, I believe that I have tracked down the cause in what appears to be a minor bug in apr_ldap_stub.c. Observe the following code snippet starting in line 48 of apr_ldap_stub.c: #if defined(NETWARE) modname = "aprldap.nlm"; #elif defined(WIN32) modname = "apr_ldap-" APU_STRINGIFY(APU_MAJOR_VERSION) ".dll"; #else modname = "apr_ldap-" APU_STRINGIFY(APU_MAJOR_VERSION) ".so"; #endif rv = apu_dso_load(&symbol, modname, "apr__ldap_fns", pool); if (rv == APR_SUCCESS) { lfn = symbol; } Because we are on a UNIX platform, the variable modname acquires the value "apr_ldap-1.so". However, because we are on PA-Risc based HP-UX 11.11, the Apache build process creates this file with the name "apr_ldap-1.sl". This in turn causes Apache to call OpenLDAP libraries with improperly initialized parameter(s), which is why we get the failed assertion in sasl.c in the OpenLDAP code base. Thankfully, the workaround is trivial. In SERVERROOT/lib/apr-util-1, I symlinked apr_ldap-1.so to apr_ldap-1.sl, and LDAP authentication works without the error described above. Am I missing something, or should I report this as a bug in bugzilla?
