--- Comment #9 from Richard Ullger ---
Backtrace limit is already set to unlimited levels so I'm not sure how to
generate the required info.
Is the following of any use?
101 args = QStringList{QStringLiteral("--xwayland"),
QStringLiteral(CMAKE_INSTALL_FULL_LIBEXECDIR "/startplasma-waylandsession")};

end = 0, array = {0x0}}, d = 0xaab5cdc0},
d = 0xaab5cdc0}}, }
