Range(1, int.MaxValue) produces negative result

IMGUI

-

Steps to reproduce:
1. Open attached project.
2. Open scene named "main".
3. In the "Hierarchy" window select "Main camera".
4. The "Test (Script)" component shows that:

"int.MaxValue" is 2147483647.
"[Range(1, int.MinValue)]" is from 1 to -2147483648.
"[Range(1, int.MaxValue)]" is from 1 to -2147483648.
"[Range(0, 2147483584)]" is from 0 to -2147483648.
"[Range(0, 2147483583)]" is from 0 to 2147483520.

Expected result:
"[Range(1, int.MaxValue)]" should be from 1 to 2147483648.

Reproduced with:
5.1.0f3, 5.2.4f1, 5.3.5f1, 5.3.5p6, 5.4.0b25.

    Unity 2018.3.x and the bug still exists.
    Workaround: use [Range(0, int.MaxValue - 64)]

    So doing further tests, the maximum number which can be used in a range before the behaviour happens is 2147483583, which I think is not fortuitous as 2147483647 - 2147483583 = 64 = 2^6

    I was becoming crazy with this! Thankfully I found this bug report.
    The issue is still there in Unity 2017.3, I honestly don't know how to fix it (in , even trying a max range using UInt32 gives a negative range.
