Hi Rebecca,
Thank you for reporting this. After further investigation I believe the issue is in the PPTT parser when it tries to report an error with the cache flags it performs an incorrect dereference of the FlagName parameter. I have filed this in bugzilla (https://bugzilla.tianocore.org/show_bug.cgi?id=3770) and sent a patch to fix this to the mailing list (https://edk2.groups.io/g/devel/message/84801), let me know if this solves the problem that you were having.
Thanks,
Chris

I noticed that with edk2 7a6e6ae9332614d386446d2a73e34b74fe66446f and
edk2-platforms 871ce778eb85825b0594b2ca3bf4c1cc795b43cc (i.e. both
latest master as of December 14th 1am UTC), running "acpiview -s pptt"
causes a synchronous exception fault:
