Dear Maintainer,
Kindly check the additional information regarding this issue which might be
helpful for analysis.
I’ve checked below binaries from the efitools:armhf package,
* Binaries can run without the exception (not fully tested, just ran the
binary to check the errors)
* HelloWorld.efi
* Loader.efi
* LockDown.efi
* ShimReplace.efi
* Binaries fails with the same exception
* KeyTool.efi
* HashTool.efi
* ReadVars.efi
* SetNull.efi
* UpdateVars.efi
Note: The Undefined OpCode exception never happens with arm64 binaries, so it's
armhf specific problem
Thanks & Regards
Shivanand K
