Interesting, so you are saying the `-Bsymbolic` is basically the default for executable?

Wouldn't that mean that, for example, LD_PRELOAD would not work for symbols in the main executable?    My understanding is that `-Bsymbolic` would prevent `LD_PRELOAD` from overriding symbols because they would be bound locally.  Although I guess I am wrong?
