Hi,
When vim start the ruby interpreter, any runtime error may cause a core dump.
To reproduce, put a bad environment variable looked by ruby:
% RUBYOPT='-r /not_extists' vim --cmd 'ruby 0'
Vim: Caught deadly signal SEGV
Vim: Finished.
[1] 32583 segmentation fault (core dumped) RUBYOPT=-r/ VIM=./runtime
src/vim -u NONE --cmd 'ruby 0'
% gdb
:(
[...]

I tried with version 1.9.3, 2.0.x, 2.1.x and 2.3.x of ruby , same issue for all.
Using ruby_options() instead ruby_process_options() fix this for me, ruby catch
this exception.
I not known if is best solution, but this improve the diagnostic.
Thanks
