Err, that'll break my module. My module is linked with Heimdal kerberos. I need Heimdal because it has proper support for SPNEGO (amnong other reasons). But if PHP or any other module is linked with a different Kerberos library (e.g. MIT) symbol collisions will occur resulting in all sorts of strange behavior. If you are going to remove RTLD_DEEPBIND, can you recommend an alternative method for linking a module so that said symbol collisions do not result? What problems are you seeing with RTLD_DEEPBIND? Perhaps it could be an extension specific ini option like: extension = mymodule.so:RTLD_DEEPBIND or extension.deepbind = mymodule.so ?
