The patch "f07a9df9af60 ArmVirtPkg: Enable stack guard" enabled stack overflow detection for ArmVirtPkg. Following this patch, running UEFI shell command 'dmpstore' resulted in a crash indicating a stack overflow. Invoking 'dmpstore' results in recursive calls to CascadeProcessVariables () which apparently consumes the available stack space and overflows.
Therefore, increase the primary core stack size.
