Samer,
Can you please provide the details on how to reproduce an incorrect stack
alignment.
It has been a long time since we have worked on this code, and I recall
reviewing the stack alignment carefully at that time.
It is possible that the code that called an EBC function has misaligned the
stack. It is also possible that use of a newer/different compiler/assemble
could be causing some issues.
Thanks,
Mike

Subject: [edk2] [PATCH] MdeModulePkg: Fix EBC DXE issue with x64 function call
alignment
Dear MdeModulePkg maintainers,
Please find the attached patch to fix a stack alignment in EBC DXE interpreter
for X64 native calls:
Fix EBC X64 native call to be 16-byte aligned. From MSDN x64 Software
Conventions:
"The stack will always be maintained 16-byte aligned,
except within the prolog (for example, after the return address is pushed),
and except where indicated in Function Types for a certain class of frame
functions."
