Recently we updated Kate text editor to use C++20. After the switch, I noticed that the flamegraph being shown in hotspot was incorrect consistently. (I am not sure if this will be reproducible in any other C++20 app)
To Reproduce
Steps to reproduce the behavior:
Build kate using kdesrc-build (needs Qt6): kdesrc-build --include-dependencies kate
Source the prefix: source /path/to/kate/build/prefix.sh
start kate via perf: perf record --call-graph dwarf kate -b -n .
