I have been trying to formulate a reasonable explanation why I am seeing the following behavior: 1) start bash with nss_ldap. 2) nss_ldap pulls in libpthread.so.1 via. some non-direct dependency - libdb41.so.1. 3) Constructor is called for libpthread.so.1 that installs signal handler wrappers. 4) libreadline.so.4 uses sigaction, but it is not binding to the strong symbol of libpthread.so.1. It is still using the older one. Is this expected? Symbols will only be bound on the immediate dependencies of what is loaded by dlopen, or should all symbols within the closure be bound? Sean
