Claim Text:
1. A method comprising: decompiling, by a processing device, a first binary representing a first instance of a system table that is associated with a guest operating system of a first virtual machine, to obtain a first string of symbols comprising a first temporary variable name, wherein the first binary is generated by a first version of a compiler; decompiling, by the processing device, a second binary representing a second instance of the system table that is associated with guest firmware of a second virtual machine, to obtain a second string of symbols comprising a second temporary variable name that is different than the first temporary variable name, wherein the second binary is generated by a second version of the compiler that is different than the first version of the compiler; and in response to determining that there is a difference between the first string of symbols and the second string of symbols, and that the difference is not due to different compiler versions and is not due to different temporary variable names, generating a signal indicating an inconsistency between the first instance and the second instance.
