EmulatorPkg Segmentation Fault in PeiLocatePpi

EmulatorPkg Segmentation Fault in PeiLocatePpi

[Michael Zimmermann]

I've compiled EmulatorPkg using build.sh for x86_64 under Arch Linux
with GCC 7.2.0 and get this abort:

Apparently, two if the Ppi services entries have invalid entries:
(gdb) print/x *PrivateData->PpiData.PpiListPtrs[3].Ppi
$4 = {Flags = 0x0, Guid = 0x0, Ppi = 0x0}
(gdb) print/x *PrivateData->PpiData.PpiListPtrs[4].Ppi
$5 = {Flags = 0x0, Guid = 0x0, Ppi = 0x0}
