Subject: [ruby-core:59535] [ruby-trunk - Bug #9321] rb_mod_const_missing	does not generate a c-return event


Issue #9321 has been updated by deivid (David Rodr��guez).


But when raising an exception from ruby, return events are emitted... Shouldn't this 2 cases be consistent?

We have had an issue reported for ruby-prof where execution times were attributed incorrectly in the call graph.

It turned out that the problem is caused by a missing c-return event for Module#const_missing.

ruby-prof simulates the ruby call stack by subscribing to line, call, c-call, return and c-return events.

Obviously, the missing return throws ruby-prof off the track.
