Hi,
When build ovmf with the latest two commits of master branch, we meet error on Red Hat 7.6 with gcc version 4.8.5, but succeed on Red Hat 8.0 with gcc version 8.2.1.
Steps:
git clone https://github.com/tianocore/edk2.git
cd edk2
git submodule init
git submodule update -recursive
OvmfPkg/build.sh -a X64 -n 64
Error log:

This bug was introduced in commit b3527dedc395 ("MdeModulePkg/DxeIpl:
Create 5-level page table for long mode", 2019-08-09).
It's being addressed in the following (pending) patch:
[edk2-devel] [PATCH 1/1] MdeModulePkg/DxeIplPeim: Relocate the operation
of PageMapLevel5Entry++
(I'm calling the issue a bug and not an invalid compiler warning because
the patch looks like an actual fix.)
Thanks
Laszlo
