If a global variable is initialised using a macro with multiple arguments, ECC incorrectly parses the statement and reports the macro arguments as variable declarations.
Example: In the following statement: STATIC INT WrongVariable = MACRO_VERSION(1, 0), NextVariable; The logic in the ECC function GetIdentifierList() interprets the above statement as declaration of three variables: 1. 'WrongVariable = MACRO_VERSION(1,' 2. '0)' 3. 'NextVariable' Following which NamingConventionCheckVariableName() reports an error for "0)" stating an incorrect variable declaration as below: "ERROR - *The variable name [0)] does not follow the rules" This patch fixes the parsing logic so that scenarios with macro initialisations are handled correctly.
