Thanks for showing me the backtrace.
I'm little confused about the result.

The backtrace shows that illegal instruction is in unknown function name.
And the function is called from `objlist_call_init()` that calls initialize
function (usually _init() is written in elf header) of dynamic link library.

I think initialize function is generated by the compiler.
If it is broken, that means all dynamic link libraries compiled by the same
compiler would fail initialization.
I think such kind of things hardly happen.

To see what instruction is illegal, Would you disassemble by the following lldb
command?

$ lldb /usr/local/bin/ghb -c ghb.core
(lldb) disassemble -f

This will show all instructions in that function.
