[Bug] Compiler fails getting value from computed float4 without debug info #2426

@zerkawei

Description

@zerkawei

The following code fails to build when disabling Debug Info in the build settings (except when using Og+ on Windows) :

let foo = float4(1,2,3,4) * 1;
let x = foo.x;

The compiler outputs the following error message :

/usr/lib/llvm19/include/llvm/IR/Instructions.h:908: llvm::Type* llvm::checkGEPType(Type*): Assertion `Ty && "Invalid GetElementPtrInst indices for type!"' failed.`

Tested on latest nightly (03/27/2026).
