If it's a real bug, you can just report what you know and leave it at that. You don't need to embellish it with random guesses about a root cause.
Okay: "I compile this input and the linker crashes."
Not okay: "I compile this input and the linker crashes. Also here's 10 paragraphs of slop about dwarf tables, which I can't even evaluate the accuracy of since I'm not an expert."
