Description
Is there an existing issue for this?
- I have searched existing issues
Current Behavior
There is currently a panic at top of tree patina-qemu + patina-dxe-core-qemu + patina. I will have all related commits in the versioning section below.
I traced this to the following commit in the patina repo - Update to patina-paging v8 - e.g. it does not panic before this commit; it does panic after this commit.

Steps To Reproduce
<Assuming all repos are cloned to c:\\src\\patina >
2. Clone top of tree patina
3. Clone top of tree patina-dxe-core-qemu
4. run cargo make q35 C:\\src\\patina\\patina to build q35's dxe-core with top of tree patina
5. clone patina-qemu
6. setup patina-qemu - e.g. stuart_setup, stuart_update,
7. run stuart_build -c .\Platforms\QemuQ35Pkg\PlatformBuild.py --FlashRom BLD_*_DXE_CORE_BINARY_PATH=C:\src\patina\patina-dxe-core-qemu\target\x86_64-unknown-uefi
8. See build error
9. In patina checkout any commit before 3bb9821 and follow the above steps again
10. Do not see build error
