Crash: cast<X>() error when two func call in together! but only any one is Success

[vec2vec2]

Description

• Scenario A: Call Tests1(DefaultMemory) only in main()-> Success
• Scenario B: Call Tests2(ret) only in main()-> Success
• Scenario A&B (The Bug): Call both in main() -> Crash (cast<X>() argument of incompatible type!)

A very strange and incomprehensible mistake

Steps to Reproduce

Actual Behavior
error: cast() argument of incompatible type!
Compiler returned: 5

Environment

• DXC 1.8.2505
• Windows10

The compiler should be rejecting this code - so marking this as an incorrect-code / diagnostics issue. No-inlined functions cannot take resource arrays as an argument.

Thanks. and I found a workaround: passing a uint ID to the [noinline] function to switch which buffer to use, instead of passing the resource array directly.
