Hi,

I am working on a BIOS sighting, which need to build SKX/ICX BIOS to test.
Build commands:
  WhitleyRpPkg\PlatformBIOSBuild.py -c SKX -b RELEASE -t VS15
  WhitleyRpPkg\PlatformBIOSBuild.py -c ICX -b RELEASE -t VS15

But the build tool always reports an unknow fatal error while processing a certain driver.
And it asks me to send email to devel@edk2.groups.io for help.
The attachment are 3 build logs for your reference.

Note:
When I first encountered this issue, I tried several times of clean build, but not work.
Then I created a new workdirectory and downloaded a new source code, it is able to build pass for 1st time, after that met the unknow fatal error as well in the following builds.
I tried to re-download a new source code, but the failure happened starting from the 1st build.
Command to download source code: edkrepo clone . DCG10nm

Till now, I am still stuck in the build issue, please help to take a look at this issue since it blocks our debug activity.

Thanks,
Fei
