ext/coverage/coverage.c (rb_coverage_start): Ensure `opt` is a hash
Ensure `opt` is a hash before using `rb_hash_lookup` to `opt`. This will prevent SEGV when an inappropriate object (i.e. an array) is passed to `opt`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59915 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
