…etry-cpp into fix-meter-context-flush
Thanks for confirming. Also calling MeterProvider->Shutdown() is now optional, as it would be called as part of MeterProvider destruction. Have added that change in this PR. |

Fixes #1676
Changes
MeterContext::ForceFlush() is incorrectly setting shutdown latch. Later when MeterContext::Shutdown() is invoked, the latch is already set, and shutdown is not done.
The PR would have merge conflict with #1673.
@ahadnagy - If you would like to test the changes, I got the segfault with with your code during MeterProvider shutdown, and this fixes that. I am hoping it was the same crash you observed :)
