Hi Thiago, I just looked at the build log at:
https://testresults.qt.io/coin/api/results/qt/qtbase/31eb60ef6fa413035971e47cc3f0eccaeba2a4dd/LinuxUbuntu_20_04x86_64QNXQNX_710arm64GCCqtci-linux-Ubuntu-20.04-x86_64-50-ab8bebDisableTests_UseConfigure/fbbf955d4168c54abbfb4dde4ba71ab3b3195ce0/build_1679395838/log.txt.gz

It includes this:

Is this the error that causes QNativeIpcKey::Type::SystemV to be the
value you mentioned?
warning: 'QNativeIpcKey::TypeAndFlags::type' is too small to hold all
values of 'enum class QNativeIpcKey::Type'

I don't know how to fix it but it might be a step in the right
direction, if it is the error.
