P3: Somewhat important Description
- With a dev build of Qt 5, check out/cherry pick https://codereview.qt-project.org/#/c/255185/9.
- Open qtdeclarative/tests/auto/qml/qqmltablemodel/qqmltablemodel.pro.
- Put a breakpoint on line 150 of qtdeclarative/src/qml/types/qqmltablemodel.cpp.
- Run the "appendRemoveRow" test (add it as an application argument).
- Start debugging.
- Jump over until you hit line 152.
- Expand the rowsAsVariantList local. It can take ~70 seconds on the first run, and ~35 seconds on each successive run within the same session.
Note that I removed -Og from qtdeclarative/src/qml as most locals (including the one I'm interested in) are <optimized out> otherwise.
