You must have a much more advanced relationship to errors than me. I don’t think I could tell the difference between 100k or 40k lines worth of errors, and it was only halfway through writing this message that I realized you might actually be talking about the size of an error? Oh no.
I suspect you'd notice simply because scrolling to the top of your history isn't sufficient anymore to find the first error. (Assuming one clears their shell history before compilation, which is very nearly required in this context...)
