When calling ->prepare_srv() callback for SSL server which depends on global "nbthread" value, this latter was not already parsed, so equal to 1 default value. This lead to bad memory accesses. Thank you to Pieter (PiBa-NL) for having reported this issue and for having provided a very helpful reg testing file to reproduce this issue (reg-test/lua/b00002.*). Must be backported to 1.8.
