>Description:
Ports linked against lua die almost immediately at startup.  For example, dns/dnsmasq with LUA set yields:

hydra% dnsmasq
zsh: bus error (core dumped)  dnsmasq
hydra% gdb `which dnsmasq` dnsmasq.core

Previous frame identical to this frame (corrupt stack?)

security/nmap's nmap executable, which also uses lua, also dies immediately in the same way, erroring in __tls_get_addr.

>How-To-Repeat:
Build dns/dnsmasq or security/nmap on sparc64
