I discovered that, the sizeof(ComparisonMode) seem to be different
depending on whether the type TComparisonMode is defined in the same
unit file or in another unit file.
Is that possible?
If the units are compiled using different settings, yes.
I cannot create a simple test file to test it because the problem only
appears in my big project.
Does FPC always produce a 4 byte variable for an enumerated types?
No, it depends on the $mode directive and the settings of the packenum
directive.
