Assertion Failure: (e->flags & EntityFlag_Overridden) == 0 in malformed input

[SaculRennorb]

Context

I'm currently porting a codebase to odin. During that process i repeatedly throw the still malformed code at the compiler to get it to tell me what to fix next.

    Odin:    dev-2024-12-nightly:cf53404
    OS:      Windows 10 Enterprise N (version: 20H2), build 19042.1466
    CPU:     Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz
    RAM:     65470 MiB
    Backend: LLVM 18.1.8

Expected Behavior

no asserts

Current Behavior

D:\a\Odin\Odin\src\check_expr.cpp(1735): Assertion Failure: `(e->flags & EntityFlag_Overridden) == 0` 
D:\a\Odin\Odin\src\check_expr.cpp(1735): Assertion Failure: `(e->flags & EntityFlag_Overridden) == 0` 
 *  The terminal process "C:\Program Files\Odin\odin.exe 'run', 'out_manual', '-linker:radlink', '-debug', '-max-error-count:999'" terminated with exit code: -2147483645. 

Steps to Reproduce

1. unzip the attached source code
2. run odin.exe run out_manual -linker:radlink -debug -max-error-count:999
3. observe assert

out_manual.zip

Since there is close to no info on this i don't feel like trying to reduce the repro case. I suspect it has to do with imgui.cpp.odin:3354, since that was my last change.
