Running on Linux (Ubuntu 21.04 kernel 5.11.0-18-generic) in debug or release-safe mode crashes at malloc_consolidate().

Running in release-fast and release-small works fine.

How to reproduce:

1. Opening any existing file

malloc_consolidate(): unaligned fastbin chunk detected
The following command terminated unexpectedly:
cd /home/batiati/IUPforZig/IUPforZig && /home/batiati/IUPforZig/IUPforZig/zig-out/bin/example 
error: the following build command failed with exit code 1:
/home/batiati/IUPforZig/IUPforZig/zig-cache/o/6cece1366aaf0a2f9f1ae0f99faff783/build /snap/zig/3678/zig /home/batiati/IUPforZig/IUPforZig /home/batiati/IUPforZig/IUPforZig/zig-cache /home/batiati/.cache/zig run

2. Clicking on "Close" button on "Find" dialog

malloc_consolidate(): invalid chunk size
The following command terminated unexpectedly:
cd /home/batiati/IUPforZig/IUPforZig && /home/batiati/IUPforZig/IUPforZig/zig-out/bin/example 
error: the following build command failed with exit code 1:
/home/batiati/IUPforZig/IUPforZig/zig-cache/o/6cece1366aaf0a2f9f1ae0f99faff783/build /snap/zig/3678/zig /home/batiati/IUPforZig/IUPforZig /home/batiati/IUPforZig/IUPforZig/zig-cache /home/batiati/.cache/zig run

Currently, we have some issues building:

• Find native include and libraries is broken with msvc ABI (zig issue 9002)
• Set exe.subsystem = .Windows; and use wWinMain entrypoint did not work with exe.linkLibC
• Do we really need linkLibC ?
• Add option to link static or use dynamic IUP libraries
• Latest zig 0.9.0-dev.315+1534cd2f8 compiles but fails running.

Figure out the better way to represent those metadata complexities:

1. IUP elements that have attributes that are applied on children;

Example:

• MDI attributes for Canvas for example

Proposals:

• Render these functions in all possible elements, allowing to set them even when they are not children of the expected element.
• Render these functions on parent element with a special signature .setXYZ(child, value); Maybe not ergonomics to declare in fluent API.

2. Complex union values

Examples:

• Colors can be an RGB triplet or a well-known alias, like "BGCOLOR", "FGCOLOR", etc.
• Tree.setValue expects an i32 representing the index, or a well-known alias, like "NEXT", "PREVIOUS", "ROOT", etc

Proposals

• Status-quo: Declare an union with each possible value, for example

pub const Color = union(enum) {
    BgColor,
    FgColor,
    Rgb: Rgb,
};

pub const Selection = union(enum) {
    Next,
    Previous,
    Root,
    Index: i32
};

• Use anytype in set; Each case may have a get behavior.
• Declare two functions, one for each type, for example setColorRgb and setColorStr`

3. Handle or HandleName attributes

Example:

• setImage and many others attribute should accept an Image or a string with the HandleName

Proposals

• Status-quo: use aways string, for example setImage(image.getHandleName())
• Use anytype in set; Each case may have a get behavior.
• Declare two functions, one for each type, for example setImage and setImageHandleName`
