Hello,

Upstream said  this error comes from GCC-16 compiler bug.

https://sourceforge.net/p/sevenzip/bugs/2604/#4f7e
> I suppose it's GCC-16 compiler bug.
> There are two different classes in 7-zip code:
> CHandlerImgProgress and CLocalProgress.
> Both these classes have same base class interface ICompressProgressInfo.
> But GCC-16 compiler doesn't like that sizes of objects of these classes also 
> are different. Maybe compiler tries to optimize the code and works 
> incorrectly.
> You can try to report that issue to GCC-16 developers.
