| | | | | | | | | | | | | | | The tests had been disabled under coverage measurement (during `ENV['COVERAGE']`), since they call `Coverage.result` which stops coverage measurement. So, we couldn't measure both C-level and Ruby-level coverage of Ruby simultaneously. In short, `./configure --enable-gcov && make exam COVERAGE=true` misses some coverages. Now, the test runs in another process. They does not stop coverage measurement, so we can now enable the tests under coverage measurement. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59724 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | There is an invariant that ISEQ_COVERAGE(iseq) must be Qnil if and only if option->coverage_enabled is false.
