What does this PR do?
This PR imports the changes from upstream
ruby/ruby#8415 into our copy of
rb_profile_frames
.I'm not entirely sure if this crash could happen for ddtrace because unlike other Ruby profilers (like stackprof) we are not (yet?) sampling from the signal handler.
Motivation:
Make sure our
rb_profile_frames
matches upstream in terms of validation/safety.Additional Notes:
N/A
How to test the change?
Good question -- I'll admit I don't quite know how to trigger the issue reported upstream. In any case, the change is quite small, so at most we'll report line 0 in a few cases where we previously weren't.
