[SPIR-V] Unhandled Exception "Name is not a simple identifier" and others, but only when running in debugger

[devshgraphicsprogramming]

Description

I was making a shader with the EXE/godbolt of the compiler, but now when I compile at runtime I get unhandled exception after unhandled exception

Steps to Reproduce

This godbolt: https://godbolt.org/z/WMsK7sP3d

Actual Behavior

Can't run with the debugger attached

Environment

• DXC version: trunk as of 17/10/24
• Host Operating System Godbolt

The whole bug seems to be caused by me defining void WhittedTask::operator()() outside the struct

Might also affect DXIL/non-spirv output

[s-perron]

I'm able to reproduce when using a debug build of the compiler. I reduced the test to:

struct WhittedTask
{
    void operator()();
};

void WhittedTask::operator()()
{
}
