Summary0035849: huge enumeration type definitions (i. e. sizeOf > 4) silently fails
DescriptionOne can define enumeration type elements that are not storeable.
Steps To Reproduceprogram bigEnum(input, output, stderr);
    enum: (null = 0, semimax = high(longWord), max = high(qWord));
    enum := max;
    writeLn(enum); // erroneously prints "semimax"
Additional InformationThe {$packEnum} directive only allows enumeration types up to and including 4 bytes. Maybe this needs an update?

Thank you. I didn’t find your issue, because I searched for issues containing “enumeration” paired with various terms (e. g. “size”, “max”, etc.)

Mark as duplicate of 0034633 and close.
