Exception when compiling shaders with the Release version built from source

[GlassBeaver]

Description
Compiling shaders with DXC built from source in the Release configuration from commit 05334a7 produces an exception.
The Debug configuration works fine.

Steps to Reproduce
Build DXC from source from commit 05334a7 in the Release configuration and try & compile any shader with it via the exe.

Actual Behavior

Exception thrown at 0x00007FFDD9302E20 (msvcp140.dll) in dxc.exe: 0xC0000005: Access violation reading location 0x0000000000000000.

This seems likely caused by https://learn.microsoft.com/en-us/cpp/porting/binary-compat-2015-2017?view=msvc-170.

I'll keep this issue open and in dormant for now, but if you find this does resolve things for you can you let us know please? Thanks!

Hi, Thanks for the link but I'll have to admit I'm not sure what I should be looking for - I'm compiling everything with the same version of VS2022, MSVC, Win 11 and Windows SDK.
