424	Encoder may produce uncompliant sps_log2_diff_max_bt_min_qt_inter_slice	fbarbier		"Depending on value of CtbLog2SizeY, the reference encoder may violate the upper boundary of sps_log2_diff_max_bt_min_qt_inter_slice. Accordingly to spec:
{{{
The value of sps_log2_diff_max_bt_min_qt_inter_slice shall be in the range of 0 to CtbLog2SizeY − MinQtLog2SizeInterY, inclusive
}}}

To reproduce the issue, we can use the merge request :
https://vcgit.hhi.fraunhofer.de/jvet/VVCSoftware_VTM/merge_requests/624

Let's reproduce with the following command lines:
{{{
git fetch https://vcgit.hhi.fraunhofer.de/fbarbier/VVCSoftware_VTM.git compliance_checks
git checkout -b fbarbier/VVCSoftware_VTM-compliance_checks FETCH_HEAD

cd build
cmake .. -DCMAKE_BUILD_TYPE=Debug
make -j 8
