Duplicated `:raise` tracepoint event when exception inside `load` call happens
A long time ago, this ruby-core change broke a test in byebug related to post-mortem debugging. See https://github.com/deivid-rodriguez/byebug/issues/165.
The problem is that after the mentioned commit, the TracePoint API raises two
:trace events when an exception happens during a
load call. As a result, byebug ends up using the second
:raise event, and that means post-mortem debugging leaves the user in an incorrect place.
I managed to workaround the issue inside byebug with https://github.com/deivid-rodriguez/byebug/pull/562, but I thought it would be worth mentioning here since it seems like incorrect behavior to me.
For what it's worth, reverting the referenced commit fixes the issue. I attach a patch doing that together with a test.
