[NOMERGE] Trying to understand crashes on -latest #643

Closed markotoplak closed 1 year ago

markotoplak commented 1 year ago

I finally figured out what is happening. We deprecated get_column_view. That should not be problematic, we would only get warning, but we have ORANGE_DEPRECATION_ERROR turned on in our tests. This should cause tests to fail, but no segfault.

Here it gets interesting. We got the deprecation warning, which has now changed to error (exception) within Qt's event handling. Exceptions there in Qt event handling: a segfault.

I am so happy to see a segfault that I can explain.

I'm glad you figured it out! This was a tricky one for sure.
