[WD21] How to fix "Overflow during assignment"?

Startbeitrag von Ola am 14.12.2016 20:39

I have one runtime warning in my app's dynamic audit,
"Overflow during assignment"
in the following code:

//StdColorBG is a global array of 24 4-byte unsigned int //Background colors
//These are constants, must not be translated.
StdColorBG = [White,DarkGray,LightRed,YellowToolhelp,DarkBlue,LightCyan, ...
Transparent,LightGray,DarkYellow,DarkGreen,LightBlue,DarkMagenta, ...
Black,DarkRed,LightYellow,LightGreen,DarkCyan,LightMagenta, ...

Can somebody please explain, why, and what should I do to get rid of the warning?

Best regards


Hi Ola,

I get this kind of errors when the value of a 8-byte int is assigned to a int i.e.
You could try using an array of 24 8-byte int.

Hi Ola,

by any chance, are you testing in 64 bits?
If yes, any system integer (like the color value) would be stored as int on 8, not 4.

Best regards

Hi Ola,

Use the 'is system int' declaration.
That way it will work on as well 32 as 64 bit systems.

Hi all,

Thanks you all for the answers.

I am developing in 32 bits, as I understand that WD might have some extra problems with 64 bits, and I already have more than my fair share of problems even with 32 bits.

I used Peter's instruction and re-specified the array as "system int", and that solved the problem.

Best regards
